Mantel-Haenszel odds ratio

Description

Mantel-Haenszel odds ratio calculation and graphing from a stratified case-control study

Usage

mhor(..., mhtable = NULL, decimal=2, graph = TRUE, design = "cohort") 

Arguments

...	Three variables viz. 'outcome', 'exposure' and 'stratification'.
mhtable	a 2-by-2-by-s table, where s (strata) is more than one
decimal	number of decimal places displayed
graph	If TRUE (default), produces an odds ratio plot
design	Specification for graph; can be "case control","case-control", "cohort" or "prospective"
