Association of calf circumference and incontinence by sex. A Calf circumference restricted cubic spline regression with 3 knots in male participants; red solid line represents association between calf circumference and incontinence, shaded areas are 95% CIs. p for non-linear < 0.001. B Calf circumference restricted cubic spline regression with 3 knots in female participants; red solid line represents association between calf circumference and incontinence, shaded areas are 95% CIs. p for non-linear < 0.001
