aBMI = body mass index. Data for BMI, muscle cross-sectional area, estimated whole-body muscle mass, total fat cross-sectional area, estimated total fat mass, visceral fat cross-sectional area and estimated visceral fat mass are presented as medians (interquartile ranges). P-values depict the statistical difference between sarcopenic and nonsarcopenic patients, with statistical significance set at P ≤ 0.05.
