This measure is most useful because it fits a normal distribution for simultaneous assessment, which starts with equal odds for both proportions (equal prior distributions), then proceeds to analyze the pooled data by contrasting the BF towards both events (log<span class="elsevierStyleHsp" style=""></span>OR<span class="elsevierStyleHsp" style=""></span><<span class="elsevierStyleHsp" style=""></span>0, log<span class="elsevierStyleHsp" style=""></span>OR<span class="elsevierStyleHsp" style=""></span>><span class="elsevierStyleHsp" style=""></span>0). It is possible to determine the quantitative weight of evidence in a similar way as referred to in the commented article1 by multiplying 10 by the logarithmic scale of the BF to confirm decisive evidence (values greater than 20) of the higher frequency group (log OR > 0), and even to reporte the negative decisive evidence of the other clinical event (logOR<0). In addition, it allows establishing the posterior probability (this measure is stable beyond the reporting of more data) given the transformation of the obtained ES: exp (log<span class="elsevierStyleHsp" style=""></span>OR)<span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>OR, and OR to probability<span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>OR/(OR<span class="elsevierStyleHsp" style=""></span>+<span class="elsevierStyleHsp" style=""></span>1) and their respective intervals to report what are realistic probabilities of participants having such medical outcomes beyond significance values.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">4</span></a> This is useful for estimating COVID-19 infection rates according to groups and comorbid clinical conditions,<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">4</span></a> such as the study replicated by Ramos-Vera<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">2</span></a> where the comparison of the proportions of cases (COVID-19 infected patients) and controls (healthy adults) reporting measures of human leukocyte antigen (HLA) genetic polymorphisms was evaluated, following the recommendation of the Bayesian Neurology Group-Texas (BNG-TX)4.
