Thresholds are presented as values of relative muscle strength (kg) divided by body weight (kg) with their respective sensitivity and specificity. The areas under the curve with the 95% confidence interval are presented. Model 1 is adjusted for age, smoking status, and alcohol intake. Model 2 is adjusted for age, smoking status, alcohol intake, and BMI. Model 3 is adjusted for age, smoking status, alcohol intake, and cardiorespiratory fitness.
