Scatterplot of SARC-F and handgrip strength by HK-MoCA at baseline and 1-year follow-up. “Jitter” was added to the SARC-F and HK-MoCA observations by adding small random quantities to show density when many observations would appear at the same location. The black line is the locally estimated scatterplot smoothing (LOESS), with the 95% confidence interval as the shaded region
