Calculate pooled incidence rate ratio and its confidence intervals with Mantel-Haenszel's method.
IRRMH(XTAB, conf.level=0.9)
XTAB |
A matrix with 4 columns. The first column is the number of cases in exposed cohort. The second column is the number of cases in unexposed cohort. The third column is the total observed person-time of exposed cohort. The forth column is the total 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. |
estimate |
Calculated point estimate of pooled incidence rate ratio 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. |
