A chi-square test for taking categorical confounding variables into account when doing a weighted sum of the associations in each of the categories, called strata.


In survival analysis, a log-rank test compares the equality of k survival functions by creating a sequence of kx2 contingency tables (k survival functions by event observed/event not observed at that time) one at each (uncensored) observed event time, and calculating a statistic based on the observed and expected values for these contingency tables. This test is also known as the Mantel-Cox (Mantel-Haenszel) test.


In meta-analyses, the strata are the various studies included.
