^aQuality of the studies were assessed with Newcastle-Ottawa Scale (NOS);
^bEWGSOP (European Working Group for Sarcopenia in Older Persons) defines sarcopenia in men as ALM adjusted for height squared < 7.25 kg/m2 combined with low hand-grip strength (< 30 kg) and/or low gait speed (< 0.8 m/s)
Asian Working Group for Sarcopenia (AWGS): participants had a lower muscle mass with a low handgrip strength of < 26 kg in men and < 18 kg in women, and/or a lower gait speed ≦ 0.8 m/s
OR, odds ratio; RR, risk ratio; HR, hazard ratio
