With a 1 month difference in duration, such as from 11 to 12, the odds of being responsive or nonresponsive are essentially even [adjusted odds ratio = 0.72]. With a one score difference in FLEX-SF, such as from 27 to 28, the odds of being responsive were almost 2.4 times greater for someone who is 28 as compared to someone who is 27 [adjusted odds ratio = 2.44]. With a 0.1 difference in slope of posterior deltoid, such as from 0.4 to 0.5, the odds of being responsive were almost 1.8 times greater for someone who is 0.5 as compared to someone who is 0.4 [adjusted odds ratio = 300]
