Since all people are unique, homeopathic medicines are prescribed to treat individuals. The effectiveness of homeopathy is yet to be proven by medical science. There is no such thing as a homeopathic vaccine, and homeopathic medicines are not a replacement for conventional medical treatment of serious diseases or infections. While homeopathic medicines are not considered in themselves harmful, homeopathy can be considered dangerous if a person relies on it as a medical treatment and uses homeopathic medicines as a replacement for conventional medical treatment when dealing with serious diseases or infections.
If you choose to consider homeopathy, you should do some research into its effectiveness. Always seek the services of a registered homeopath and tell your doctor if you are planning to start any new treatment, including homeopathy.
Lack of evidence of effectiveness of homeopathy The effectiveness of homeopathic preparations is disputed within medical science. Scientists question how a highly diluted substance could retain any biological effect. NHMRC concluded there is no reliable evidence that homeopathy is effective for any health condition. People who choose homeopathy may put their health at risk if they reject or delay treatments for which there is good evidence for safety and effectiveness. People who are considering whether to use homeopathy should first get advice from a registered health practitioner.
Those people who choose to use homeopathy should tell their doctor and keep taking any prescribed treatments. Research conducted by the highly regarded Cochrane reviews which examine the most rigorously conducted clinical research trials also has failed to find evidence of the benefit of homeopathy beyond the placebo effect. Immunisation is a medical term and refers to the process by which the body is stimulated to develop resistance to a variety of infections.
Vaccines are made from germs and work by stimulating the body to form antibodies specialised germ-fighting cells to produce immunity. Homeopathic medicines are not based on specific antibody or germ-fighting cell formation and are not an acceptable alternative to conventional vaccines. The Victorian Department of Health continues to advise parents of their responsibility to have their children immunised in accordance with Australian Government recommendations. Laws and regulation of homeopathic medicines Homeopathic medicines are made from a variety of sources, such as plants, animals and minerals.
Statistical analysis Data preparation For a continuous main outcome measure, the mean, standard deviation SD and number of subjects were extracted for homeopathy and placebo groups and the unbiased standardised mean difference SMD calculated, so that a negative SMD reflected a difference in favour of homeopathy. We did not adjust values to compensate for any inter-group differences at baseline.
For a dichotomous main outcome measure, the number of subjects with a favourable outcome and the total number of subjects in each group were extracted to enable calculation of the odds ratio OR , with values greater than 1 reflecting a difference in favour of homeopathy. For a given trial comprising more than two study groups, only the data concerning comparisons between non-individualised homeopathy and placebo were extracted from the paper.
For the pooled meta-analysis, a single measure of effect size was required to enable pooling of all relevant trials: ORs were transformed to SMD using a recognised approximation method [ 14 ]. This is a deviation from the protocol, which stated that SMD would be transformed to OR, as in a previous paper [ 2 ]. SMD and OR are equally valid statistics. Whichever of these two metrics is used, their results are interchangeable and their interpretation is identical. The I 2 statistic was used to assess the variability between studies: it gives the percentage of the total variability in the estimated effect size which is composed of between-study heterogeneity plus sampling variability that is attributable to heterogeneity.
All statistical analyses were carried out in R version 3. As recognised by Cochrane, some issues suitable for such analysis are identified during the review process itself [ 22 ]. Thus, we additionally carried out sub-group analysis depending on whether h a trial had investigated a combination, an OTC complex, an isopathic or a single remedy.
RCT nomenclature for clinical conditions and their categories was previously characterised [ 11 ] Footnote 2. Results Included studies The PRISMA flowchart from the original comprehensive literature search up to and including was published previously [ 11 ]. Footnote 3 Four-hundred and fifty-four remained after removal of duplicates. After excluding 95 due to type of record book chapter, thesis, abstract and other minor article , Three-hundred and fifty-nine full-text records were then assessed for eligibility.
Two-hundred and eighty-seven were excluded for the general reasons summarised in Fig. Footnote 4 The finally remaining 72 records 75 RCTs were thus included in this systematic review; data were not extractable from 21 of those, leaving 51 records 54 RCTs available for meta-analysis—see Additional file 2 for details of the 21 records excluded from meta-analysis. Each of 52 RCTs studied a condition that was acute in nature; each of 23 studied a chronic condition.
Seventeen trials were free of vested interest; 24 trials were not free of vested interest; 34 trials did not enable certainty in this assessment. Table 1 Demographic data for 75 randomised controlled trials RCTs of non-individualised homeopathy: 21 excluded from meta-analysis shown by italics at first author's name Full size table Summary of findings For each trial, Table 2 includes details of the sample size, the identified main outcome measure and whether dichotomous or continuous and the study end-point.
A power calculation was carried out for 28 of the trials. ITT was the basis for analysis in 21 trials. Mean attrition rate was The main outcome variable was dichotomous in 25 studies and continuous in the other The total sample size for the 54 meta-analysable trials was ; the median sample size was Meta-analysable studies included 45 different main outcome measures and for an end-point that ranged from 6 h to 6 months.
Table 2 also indicates the 25 analysed trials in our study that we have in common with those included in the meta-analysis data reported by Shang et al. Table 2 Summary of findings table: 21 excluded from meta-analysis shown by italics at first author's name Full size table Risk of bias and reliable evidence Table 3 provides the risk-of-bias details for each of the 75 trials, and sub-divided by: a the 54 that could be included in meta-analysis; b the 21 that could not be included in meta-analysis.
Domains IV completeness of outcome data , V selective outcome reporting and VI other sources of bias presented the greatest methodological concerns. Sixteen of 30 trials that were high risk of bias for domain V were so because their data were not extractable for meta-analysis see Study selection for meta-analysis above. A summary risk-of-bias bar-graph is shown in Additional file 3. Each of the other 51 trials had uncertain or high risk of bias in important methodological aspects, and may be regarded as non-reliable evidence: 23 trials were classed as uncertain risk of bias; 28 were classed as high risk of bias.
Thirteen of the 21 were seriously flawed in more than one domain of assessment i. Meta-analysis The pooled SMD random-effects model for all 54 trials was —0. Pooled effects estimate shown for fixed-effect and random-effects model. W weighting Full size image The original data extracted per trial continuous or dichotomous , together with the correspondingly calculated SMD or OR, are illustrated in Additional files 4 a and b. Of the 31 trials with continuous data, 9 had an effect statistically significantly favouring homeopathy i.
Of the 23 trials with dichotomous data, 6 had an effect statistically significantly favouring homeopathy i. Evidence of publication bias, toward studies favouring homeopathy, was apparent from the funnel plot Fig.
A meta-regression was performed to test specifically for within-group differences for each sub-group. Analysis by clinical condition Clinical conditions Meta-analysis was possible for eight clinical conditions, each analysis comprising two to five trials Fig.

If the result of new trials were to show no difference between homeopathy and placebo, we would have to add trials with no effect with patients in each in order to balance the two. Vol 1 short version. Brussels: European Commission, HMRG report with overview of clinical research in homeopathy, identified controlled clinical trials.
They selected the highest quality randomized control trials, which included a total of patients for a meta-analysis. This meta-analysis resulted in a p-value of 0. Homeopathic Medicine Research Group. Placebo effect sizes in homeopathic compared to conventional drugs — a systematic review of randomised controlled trials. Each trial was matched to three placebo-controlled double-blind RCTs from conventional medicine mainly pharmacological interventions involving the same diagnosis.
Matching criteria included severity of complaints, choice of outcome parameter, and treatment duration. Outcome was measured as the percentage change of symptom scores from baseline to end of treatment in the placebo group.
