Previous trajectories of timed stair-climb (A), timed walk (B), and timed sit-to-stand (C) test results by peripheral neuropathy status in 2008 in the peripheral neuropathy substudy, Michigan Study of Women's Health Across the Nation. Results were adjusted for race/ethnicity and baseline body mass index. Dashed lines represent trajectories for women with peripheral neuropathy, solid lines represent trajectories for women without peripheral neuropathy, and dotted lines represent the 95% confidence intervals for trajectories.
