We used the signed rank and the exact McNemar’s test to compare pretest/posttest information. We further examined the effect of the DA on screening decisions among older women stratifying by life expectancy (≤9 vs. >9 year life expectancy).31 (link)We examined whether the acceptability of the DA differed by educational attainment using bivariable statistics. We aimed to recruit 42 patients to detect a moderate effect size (0.6 times the estimated standard deviation) of the DA on patient knowledge and decisional conflict assuming within-patient correlation of 0.1. We performed a complete case analysis. All analyses were completed using SAS statistical software, version 9.3 (SAS Institute Inc., Cary, NC).
