Trend of variables after lung transplant in patients with and without sarcopenia. a The trend in the cross-sectional area of erector spinae muscle normalized to body surface area (cm²/m²), b % predicted hand-grip (HG) strength, c % predicted 6-min walk distance (6MWD), d body-mass index (BMI)(kg/m2) and e forced expiratory volume in the first second (FEV1)(L) were shown by months after transplant. The change at each annual assessment was compared to the first full assessment normally done in 2- or 3- months after transplant. Sarcopenia was shown in red solid line (n = 19) and non-sarcopenia in blue dashed line (n = 36). The difference between sarcopenia and non-sarcopenia was calculated with Mann–Whitney U test (MWU), described below the line graph. NS, not significantly different, *p < 0.05, **p < 0.01, ***p < 0.005 and ****p < 0.001
