S1 represents stratum 1 (age at follow-up of 5 years > 50 years), S2 represents stratum 2 (age at follow-up of 5 years <= 50 years), OR1 and OR2 represent the odds ratio in S1 and S2 respectively, pBDTT represents the p-value obtained using the Breslow-Day-Tarone test (BDTT), ORcrude represents the crude (unadjusted) odds ratio, ORMH represents the adjusted (unconfounded) odds ratio computed using the Mantel-Haenszel formula, pMHT represents the p-value obtained using Mantel-Haenszel test (MHT) and CM represents the magnitude of confounding. F, female; M, male.
