CI, confidence interval; BMI, body mass index; BC, brachial circumference; FC, femoral circumference BC is the brachial circumference of dominant arm. The mean FC is the mean circumference of both femurs. A larger FC indicates a larger circumference for both femurs. A smaller FC indicates a smaller circumference for both femurs. The grip strength represents the grip strength of the dominant arm. The odds ratio and P values were obtained by a univariate logistic regression analysis.
