Differences between baseline and change from baseline at 3, 6, and 12 months between the Durham Veterans Affairs parent site and the new programs combined for (A) usual gait speed, (B) number of chair stands completed in 30 seconds, (C) 6-minute walk distance, and (D) 8-foot up and go test. The dotted line indicates a threshold for high risk of loss of independence for the sex and mean age of the study sample. Above the line indicates better function except for the 8 foot up and go test. Models were limited to participants with baseline and at least one follow-up and included control for the baseline value of variable of interest. Samples sizes were n=163 at baseline for Durham and n=127, n=106, and n=84 for each successive timepoint and n=336 at baseline for all other sites combined and n=294, n=213, and n=128 for each successive timepoint. Some sites did not have time to accrue participants for 12-month follow-up. P-values are shown for the difference between Durham and all other sites at each timepoint.
