FEV1: forced expiratory volume in 1 s; HGS: handgrip strength; ASMI: appendicular skeletal muscle mass index. Model 1 was adjusted for age and sex; model 2 was model 1 plus total body fat (%), height and smoking status. #: height is only included in the HGS model due to ASMI already being calculated based on height (m2).
