Phase angle reference values. a, b and c represent the distribution of phase angle values according to age, BMI and sex. Vertical dashed lines represent lower phase angle reference value in healthy adult population. d shows the distribution of the standardized phase angle, z score, [z score = (observed phase angle-mean reference phase angle)/SD reference phase angle] for specific age, sex and BMI categories. BMI | Body mass index (kg/m2). F | Female. M | Male. SD | Standard deviation
