78,934 Citations1977J. Richard Landis, Gary G. Koch
A general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies is presented and tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interob server agreement are developed as generalized kappa-type statistics.
GastroenterologyIs there publication bias in the reporting of cancer risk in Barrett's esophagus?
736 Citations2000Nicholas J. Shaheen, Melissa A. Crosby +2 more
There was a strong correlation between cancer risk and the size of the study, with small studies reporting much higher risks of cancer than larger studies, and publication bias may be overestimated in the literature due to publication bias.

The data indicate that Barrett's esophagus complicates gastroesophageal reflux more often than previously believed.
GastroenterologyA critical review of the diagnosis and management of Barrett’s esophagus: the AGA Chicago Workshop1 1Members of the workshop composed a group of international experts in BE from gastroenterology, surgery, pathology, molecular biology, outcomes, and epidemiology.

A definitive set of reflux-associated histologic changes could not be defined from the small number of biopsy specimens examined in the present study, because these changes are nonspecific.
