In statistics, the Cochran–Mantel–Haenszel test (CMH) is a test used in the analysis of stratified or matched categorical data.It allows an investigator to test the association between a binary predictor or treatment and a binary outcome such as case or control status while taking into account the stratification. [1]
A common procedure for detecting DIF is the Mantel-Haenszel (MH) approach. [13] The MH procedure is a chi-squared contingency table based approach which examines differences between the reference and focal groups on all items of the test, one by one. [14]
The test is sometimes called the Mantel–Cox test. The logrank test can also be viewed as a time-stratified Cochran–Mantel–Haenszel test . The test was first proposed by Nathan Mantel and was named the logrank test by Richard and Julian Peto .
Cochran-Mantel-Haenszel test allows to test the association between a binary outcome and a binary predictor while taking into account stratification with arbitrary strata size. When its conditions of application are verified, it is identical to the conditional logistic regression score test .

Emails sent to government workers at numerous agencies gave employees 10 days to report if a colleague's job relates to diversity, equity and inclusion efforts.
According to the Dictionary of the Scots Language, a modern compilation of Scots words past and present, hurkle-durkle means “to lie in bed or to lounge after it’s time to get up or go to work.”
Other common approaches include the Mantel–Haenszel method [146] and the Peto method. [ 147 ] Seed-based d mapping (formerly signed differential mapping, SDM) is a statistical technique for meta-analyzing studies on differences in brain activity or structure which used neuroimaging techniques such as fMRI, VBM or PET.
