ORcmh: Odds Ratio of two groups with strata by CMH method

In sasLM: 'SAS' Linear Model

Odds Ratio of two groups with strata by CMH method

Description

Odds ratio and its score confidence interval of two groups with stratification by Cochran-Mantel-Haenszel method

Usage

  ORcmh(d0, conf.level=0.95)

Arguments

d0	A data.frame or matrix, of which each row means a strata. This should have four columns named y1, n1, y2, and n2; y1 and y2 for events of each group, n1 and n2 for sample size of each strata. The second group is usually the control group.
conf.level	confidence level

Details

It calculates odds ratio and its score confidence interval of two groups. This can be used for meta-analysis also.

Value

The following output will be returned for each stratum and common value. There is no standard error.

odd1	odd from the first group, y1/(n1 - y1)
odd2	odd from the second group, y2/(n2 - y2)
OR	odds ratio, odd1/odd2. The point estimate of common OR is calculated with MH weight.
lower	lower confidence limit of OR
upper	upper confidence limit of OR
