  1. The baseline characteristics of participants were summarized as mean ± standard deviation or median (interquartile range) for continuous variables and proportion (%) for categorical variables according to with or without CTM. The level of significance was accepted at P < 0.05.
  2. CTM, chronic thyrotoxic myopathy; non-CTM, non-chronic thyrotoxic myopathy; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; AMA, arm muscle area; TMA, Thigh muscle area; ULFT, upper limb fatigue test; LLFT, lower limb fatigue test; SUT, squat-up.
