Heatmap of the correlation matrix between the 60 metrics of physical activity identified as potentially differentiating between participants with RA and non-RA controls. The magnitude of correlation is represented by both the color and the size of each square. accel., acceleration; AUC, area under the curve; avg., average; cont., continuous; m<i>g</i>, milligravities; MVPA, moderate-to-vigorous physical activity; M10, midpoint time of the most-active 10 hours; prob., probability; RA, rheumatoid arthritis.
