A genome-wide association study demonstrates significant genetic variation for fracture risk in Thoroughbred racehorses [PDF]
, 2014 Background: Thoroughbred racehorses are subject to non-traumatic distal limb bone fractures that occur during racing and exercise. Susceptibility to fracture may be due to underlying disturbances in bone metabolism which have a genetic cause.

Generalized cochran-mantel-haenszel test statistics for correlated categorical data [PDF]
Communications in Statistics - Theory and Methods, 1997 Three new test statistics are introduced for correlated categorical data in stratified R×C tables. They are similar in form to the standard generalized Cochran-Mantel-Haenszel statistics but modified to handle correlated outcomes. Two of these statistics are asymptotically valid in both many-strata (sparse data) and large-strata limiting models.

An Adaptive Mantel–Haenszel Test for Sensitivity Analysis in Observational Studies
Biometrics, 2016 SummaryIn a sensitivity analysis in an observational study with a binary outcome, is it better to use all of the data or to focus on subgroups that are expected to experience the largest treatment effects? The answer depends on features of the data that may be difficult to anticipate, a trade-off between unknown effect-sizes and known sample sizes.
