GLM repeated measures analysis was conducted with MBI scores at four time points by gender, where 1 = males and 2 = females. The within-subjects test indicates that there is a significant time effect. MBI scores do change over time for both sexes, worst at admission and then improved at 3-month and 12-month follow-up.
