Fig. 1

Self-reported slowness and weakness criteria prevalence by objective counterpart measure values. Plots show the probability of being positive on the self-reported criterion as a function of the performance-based counterpart used to assess slowness or weakness in the original PFP, estimated using a smoothing spline with 5 degrees of freedom. Panels going left to right respectively are A and D for slowness (difficulty walking ½ mile on y-axis, measured gait speed on x-axis), B and E weakness (difficulty transferring or gripping on y-axis, measured grip strength on x-axis), and C and F our alternative weakness comparison (difficulty transferring, gripping, or lifting on y-axis, measured grip strength on x-axis). Females are shown at the top and males at the bottom. Vertical lines show the performance-based cutoff defining having the criterion (values less than line on the x-axis)
