Often, the prognostic ability of a factor is evaluated in multiple studies. Two applications are presented. Introduction A prognostic factor is any measure that, among people with a given health condition, is associated with a subsequent clinical outcome 1 , 2.

For example, in many cancers, tumour grade at the time of histological diagnosis is a prognostic factor because it is associated with time to disease recurrence or death; those with a higher tumour grade have a worse prognosis. Prognostic factors thus distinguish groups of people with a different average prognosis, and this allows them to be useful for clinical practice and health research.

For example, they can help define disease at diagnosis, inform clinical and therapeutic decisions either directly or as part of multivariable prognostic models , enhance the design and analysis of intervention trials and observational studies as they are potential confounders and may even identify targets for new interventions that aim to modify the course of a disease or health condition.

Given their importance, there are often hundreds of studies each year investigating the prognostic value of one or more bespoke factors in each disease field. Moreover, publication bias and sensitivity analysis were evaluated. Results The findings of the included studies were consistent in stating the contribution of comorbidities, gender, age, smoking status, obesity, acute kidney injury, and D-dimer as a risk factor to increase the requirement for advanced medical care.

The analysis results showed that the pooled prevalence of mortality among hospitalized patients with COVID was Older age has shown increased risk of mortality due to coronavirus and the pooled odds ratio pOR and hazard ratio pHR were 2.

Conclusion Chronic comorbidities, complications, and demographic variables including acute kidney injury, COPD, diabetes, hypertension, CVD, cancer, increased D-dimer, male gender, older age, current smoker, and obesity are clinical risk factors for a fatal outcome associated with coronavirus. Keywords: Comorbidities, Demographic characteristics, Funnel plot, Heterogeneity, Publication bias, Sensitivity analysis Introduction The novel coronavirus nCoV is a newly emerging disease that was first reported in China, and has subsequently spread worldwide.

It is a major challenge for many countries to identify what measures could be used to avoid death or severe illness. The challenge of COVID is very high globally due to the complexity of its transmission and a lack of proven treatment [ 5 , 6 ]. It will be more disastrous for middle and low-income countries because of their high illiteracy, a very poor health care system, and a scarce Intensive Care Unit. A series of studies have reported clinical characteristics of COVID critical illness [ 7 ] and severe illness [ 8 ] patients.

The clinical features and risk factors considered aims for the identification of risk factors associated with fatal outcomes. Accordingly one might not exhaustively study all possible risk factors. In every study, the considered risk factors vary in number and type. Based on the literature review we studied the commonly reported risk factors such as hypertension, diabetes, chronic obstructive pulmonary disease, dyspnoea, history of substance use, gender, acute respiratory distress syndrome ARDS , history of smoking, older age, albumin, and D-dimer [ 9 — 12 ].

We assume that the probabilities for the two groups are. By default, orcalc uses the last group as the reference or omitted group. The program shows the formula for calculating the odds ratio, which is the odds of group 2 divided by the odds of group 1. To calculate the odds for group 2,. The odds for group 1 is calculated by dividing. The following shows the output from issuing the orcalc command, assuming that the predictor variable has three categories whose probabilities are.

Two odds ratios are calculated, one comparing group 2 to group 1, and one comparing group 3 to group 1. Again, the last group is used as the reference group. This example is the same as the one above, except that we have used the ref option to use the second group as the reference group.

You will notice that this greatly changes both odds ratios. Be careful about language: This is called the odds ratio; it is called that because it is the ratio of two odds. Some people call the odds the odds ratio because the odds itself is a ratio. That is fine English, but this can quickly lead to confusion. If you did that, you would have to call this calculation the odds ratio ratio or the ratio of the odds ratios. It is the language, and not the math, that leads to the confusion.

When we say that in a logistic model, the odds ratio is constant, we mean o evaluated at one point is constant.
