This utility provides a Mantel-Haenszel chi-squared test for stratified data.

Inputs are:

  • - two 2 x 2 tables of stratified data;
  • - confidence level required; and
  • - desired precision of answers.

Outputs include:

  • - Chi-square statistic and corresponding P-value and odds ratio (with confidence limits) for each table;
  • - M-H Chi-square statistic and P-value and overall odds ratio and confidence limits;
  • - Woolf's test for homogeneity of odds ratios; and
  • - a plot of odds ratios and associated confidence limits.
