To calculate an odds ratio, you must have a binary outcome. And you’ll need either a grouping variable or a continuous variable that you want to relate to your event of interest. Then, use an OR to assess the relationship between your variable and the likelihood that an event occurs. Wh...

A Most Odd Ratio:: Interpreting and Describing Odds Ratios Results ORs are often interpreted as though they have the same meaning as RRs (i.e., ratios of probabilities rather than ratios of odds), an ... A Persoskie,RA Ferrer - 《American Journal of Preventive Medicine》 被引量: 3发表...

This study was not powered to look at that difference, although the odds ratio favors the combination with obinutuzumab over acalabrutinib alone. But this study was not powered to look at that difference. So, for me, that’s still not convincing evidence that anti-CD20 adds any value to BT...
The four most critical factors for determining sample size for gene by environment interaction studies are the odds ratio for the interaction, the prevalence for exposure in the population, the prevalence of the genotype in the population, and the case to control ratio. In general, sample sizes ...
This article 1) provides a practical overview of important measures of effect typically used in health studies, including absolute risk, absolute risk reduction, relative risk, relative risk reduction, odds ratio, hazard ratio, and number needed to treat; 2) covers the use and misuse of these ...
The OR is the ratio of the exposure odds (O) among the case group to the exposure odds among the control group (Figure 2): Ocase = A/C, Ocontrol = B/D, OR = Ocase/Ocontrol), and it is interpreted similarly to the RR. An OR equal to 1 indicates no association, an OR less...
I ran an analysis using Lanza's method for distal variables and I'm struggling to interpret the output. I'm aware of how the odds ratios are computed from the probabilities but I'm unsure which odds ratios to extract. In my analysis I have five drinking classes and am exploring a ...
