an increased odds of achieving a BCVA letter score >70 letters at 100 weeks compared to those with an intact ellipsoid zone, since the OR is greater than 1 (OR 2.26, 95% CI 1.14 to 4.48;p = 0.02) [9]. The narrower the CI, the more precise the estimate is; and the smaller ...
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 ...
How do odds work?An odds ratio is the probability of something happening versus it not happening i.e. $latex frac{p}{1-p}$Odds can be expressed in nicer ratios, e.g. 2:1, where the sum of the two numbers represents the denominator for working out each probability. So it becomes (...
