Relative Risk and Odds Ratios are often confused despite being unique concepts. Why? Well, both measure association between a binary outcome variable and a continuous or binary predictor variable. And unfortunately, some people use the names interchangeably. They shouldn’t be because they have diffe...

3.2%. Moreover, in the largest global Phase III gastric cancer trial, CheckMate-649, nivolumab combined with chemotherapy showed superior OS compared to chemotherapy alone, reducing the risk of death by 20%. The combination therapy performed slightly better in patients with higher PD-L1 scores [...
4 Women living with HIV (WLHIV) do not seem to be at an increased risk of developing breast cancer.5,6 However, once they have received a diagnosis of breast cancer, WLHIV have worse outcomes. Analyses of the National Cancer Database; Surveillance, Epidemiology, and End Results (...
However, the pathophysiology of LVH has not been completely elucidated in patients with gradually decreasing renal function due to the complexity of traditional and non-traditional cardiovascular risk factors. The clinical course and patterns of LVH are also determined by the stage of renal dysfunction...
Recognizing the key role of molecular evolutionary mechanisms in virus-host interactions, we see a growing understanding of their impact on viral emergence, host specialization, and the likelihood of host jumps, altering disease transmission and epidemiology. The primary mode of Zika virus (ZIKV) ...
Methods For both multiplicative and additive RR models, we present formulae for indirect adjustment of observed RRs for unmeasured potential confounding variables when there are multiple categories. In addition, we suggest an alternative strategy to identify the characteristics that the confounder must ...
