Bayesian test for hazard ratio in survival analysis. [PDF]

open access: yesSpringerplus, 2016
Over the decades, testing for equivalence of hazard functions has received a wide attention in survival analysis. In this paper, we proposed a Bayesian test to address this testing equivalence problem, Most of all, proposed test is methodologically flexible so that a procedure determining weights is not required when the proportional assumption is ...

What’s the Risk: Differentiating Risk Ratios, Odds Ratios, and Hazard Ratios? [PDF]

open access: yesCureus, 2020
Risk ratios, odds ratios, and hazard ratios are three common, but often misused, statistical measures in clinical research. In this paper, the authors dissect what each of these terms define, and provide examples from the medical literature to illustrate each of these statistical measures.
