Body composition correlations in rheumatoid arthritis (RA) and prediabetes. Scatter plot depicting the relationships between (a) change in lean mass (y-axis) and change in muscle myostatin (x-axis) following exercise training in RA (r = −0.39, P = 0.23); (b) change in lean mass and change in muscle myostatin in prediabetes (PD) (r = −0.92, P = 0.0005), Fisher r-to-z P = 0.026; (c) change in lean mass and change in muscle interleukin-6 (IL-6) in RA (r = −0.65; P = 0.023); (d) change in lean mass and change in muscle IL-6 in prediabetes (r = −0.98, P <0.0001), Fisher r-to-z P = 0.0004; (e) change in lean mass and change in muscle IL-1β in RA (r = −0.63; P = 0.049); (f) change in lean mass and change in muscle IL-1β in prediabetes (r = −0.38, P = 0.31), Fisher r-to-z P = 0.516; (g) change in lean mass and change in muscle tumor necrosis factor-alpha (TNF-α) in RA (r = −0.68; P = 0.023); (h) change in lean mass and change in muscle TNF-α in prediabetes (r = −0.82, P = 0.002), Fisher r-to-z P = 0.516; (i) change in body fat percentage and change in muscle TNF-α in RA (r = 0.67; P = 0.022); and (j) change in body fat percentage and change in muscle TNF-α in prediabetes (r = −0.07, P = 0.88), Fisher r-to-z P = 0.095
