To analyze change in QOL over time, minimally important difference in EQ-5D was defined as 0.07.（29）We then analyzed whether each participant had improvement (increase of $0.07),worsening (decrease of $0.07), or had no change (#0.07) in QOL from 3 to 12 months using an ordinal logistic regression model.We used a proportional odds approach to model the effect of sex (female vs male) across these 3 ordinal levels of change (i.e., improved, no change, worsened). This model assumes that the odds ratio (OR) describing the sex difference in the change in QOL over time is proportional (i.e., the same) across all possible dichotomizations of the outcome variable. In other words, the odds are the same for the comparison between improved EQ-5Dvs no change or worsened EQ-5D (combined) as it is for improved or no change in EQ-5D (combined) vs worsened EQ-5D. The adjusted model included the same variables as was included in step 5 of the 12-month model (i.e., demographic, socioeconomics, clinical, and 3-month variables). All statistics were performed with SAS 9.2 (SAS Institute, Cary, NC). 原文来自 Sex differences in quality of life after ischemic stroke.Bushnell CD, Reeves MJ, Zhao X, Pan W, Prvu-Bettger J, Zimmer L, Olson D, Peterson E.Neurology. 2014 Mar 18;82(11):922-31. 引用文献29来自Walters SJ, Brazier JE.
