Trials were patients merely had BLT as active treatment indicated a higher effect size (Hedges`s g= -0.51, 95%CI =-0.70 to -0.32 and p=0.001) than studies with concomitant psychopharmacological treatment (Hedges`s g= -0....

Meta-analysis of rare event studies has recently become a subject of controversy and debate. We will argue and demonstrate in this paper that the occurrence of zero events in clinical trials or cohort studies, even if zeros occur in both arms (the case of a double-zero trial), is less problematic, at least from a statistical perspective, if the available statistical tools are applied in the app...

The Mantel-Haenszel estimate for the odds ratio (and its logarithm) in stratified case control studies lacked a generally acceptable variance estimate for many years. The Robins-Breslow-Greenland estimate has met this need, but standard textbooks still do not provide an explanation of how it is derived. This article provides an accessible derivation which demonstrates the link between the Robin...

For more than two decades, the Mantel-Haenszel (MH) procedure has been used to detect differential item functioning (DIF). A bibliometric study of this use of the MH procedure was conducted in order to better understand the current state of the research activity in the area (in terms of quantitative indicators and impact). Initially, we drew up a map of scientific output about this research are...

The metafor package provides functions for conducting meta-analyses in R. The package includes functions for fitting the meta-analytic fixedand random-effects models and allows for the inclusion of moderators variables (study-level covariates) in these models. Meta-regression analyses with continuous and categorical moderators can be conducted in this way. Functions for the Mantel-Haenszel and ...

The logrank test is a well-known nonparametric which often used to compare the survival distributions of two samples including right-censored observations, it also known as Mantel-Haenszel test. Gρ family tests, generalizes by using weights assigned observations.

The Cochran–Mantel–Haenszel (CMH) tests apply when every treatment is present on block or stratum and responses are categorical. This chapter explains the most elementary of incomplete designs, balanced design (BIBD), in part to see how CMH methods can aid analysis for such designs. relationship shows that adjusted Durbin test ANOVA F essentially same test, so both equality mean ranks, not mere...
