The results of their analyses are reported in Table 1. Table 1. Unadjusted, stratified, and Mantel-Haenszel effect estimates from the hypothetical study on obesity and gallstones. Unadjusted Estimates Estimates for the subsample with a low cholesterol diet Estimates for the subsample with a high cholesterol diet Mantel-Haenszel estimates Odds ratio 3.24 3.01 2.83 2.92 Risk difference 0.20 0.17 0.17 0.17 Based on the information in Table 1 report the following information: Was it appropriate to estimate an odds ratio using Mantel-Haenszel methods (yes/no)?
