  1. According to thoracic SMI level, the subjects were divided into two groups: low muscle mass group and normal muscle mass group. There were significant differences in CCI, duration of stay, Alb and Hb between the two groups (*P < 0.05, ΔP < 0.05, P < 0.05). There was no significant difference between the sexes (P > 0.05).
