PURPOSE The efficacy of the reduction time (tau) after castration as a prognostic factor was examined by comparing to Gleason score. MATERIALS AND METHODS The change of prostatic volume after castration was observed from the castration to 3 months after in 24 cases of prostatic cancer. Prostatic volume was examined by transrectal ultrasonography of the prostate. Survival curves was calculated...
This paper proposes two new Mantel-Haenszel test statistics for correlated binary data in 2 x 2 tables that are asymptotically valid in both sparse data (many strata) and large-strata limiting models. Monte Carlo experiments show that the statistics compare favorably to previously proposed test statistics, especially for 5-25 small to moderate-sized strata. Confidence intervals are also obtaine...
S Three new test statistics are introduced for correlated categorical data in strati ed R C tables. They are similar in form to the standard generalized Cochran-Mantel-Haenszel statistics but modi ed to handle correlated outcomes. Two of these statistics are asymptotically valid in both many-strata (sparse data) and large-strata limiting models. The third one is designed speci cally for the man...
in order to determine the occurrence of endometriosis in patients with uterine myoma and in those with polycystic ovarian disease (pcod) compared to controls, 540 infertile patients were first divided into two age groups of 20-29 and 30-39. then each group was subdivided to patients with 1) uterine myoma, 2) pcod, and 3) no uterine myoma or pcod (control subgroup). the occurrence of endometrios...
Generalization of Mantel-Haenszel procedure for 2 x J (J > 2) tables is reviewed. Included are generalized Mantel-Haenszel tests, estimators for a common odds ratio, and generalized Breslow-Day test for the homogeneity of odds ratios across the strata.-Environ Health Perspect 102(Suppl 8): 57-60 (1994)
The asymptotic power of the Mantel-Haenszel test is compared to that of its competitors.
