Per our hypothesis, physical function scores improved at 6 months in those who lost 5% of their weight compared to those who didn’t (p=0.02), and the difference between groups was sustained at 12 months (p=0.04). PF improved 4.4 points at 6 months and 3.6 points at 12 months in the group who lost 5% of their weight, vs 0.3 and 0 points, respectively, in the group who did not. These differences approach, but do not reach, the pre-established minimally important difference of 5 points.
