IRDMH: Calculate pooled incidence rate difference and its confidence intervals with Mantel-Haenszel's method

Description

Calculate pooled incidence rate difference and its confidence intervals with Mantel-Haenszel's method.

Usage

IRDMH(XTAB, conf.level=0.9)

Value

estimate

Calculated point estimate of pooled incidence rate difference with Manterl-Haenszel's method.

conf.int

A numeric vector of length 2 to give upper/lower limit of confidence intervals.

conf.level

Simply return the value of given conf.level.

Arguments

XTAB

A matrix with 4 columns. The first column is the incidence in the exposed cohort. The second column is the incidence in the unexposed cohort. The third column is the observed person-time of exposed cohort. The forth column is the observed person-time of unexposed cohort. Rows should be composed of different strata or studies.

conf.level

Probability for confidence intervals. Default is 0.9.
