  • 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.
