TTR and sarcopenia: The results indicated that sarcopenia (OR = 8.018, 95% CI 2.479∼25.932, P < 0.001), age (OR = 1.152, 95% CI 1.084∼1.224, P < 0.001), prealbumin level (OR = 0.002, 95% CI 0.000∼0.501, P = 0.028), social support (OR = 0.887, 95% CI 0.798∼0.985, P = 0.025), and MQSGA score (OR = 1.300, 95% CI 1.096∼1.541, P = 0.003) were identified as influencing factors (Table 3).
