Measurement of the sagittal abdominal diameter by use of a sliding-beam caliper in NHANES, 2011–2012.

Population mean and median (50th percentile) values with selected percentiles of the sagittal abdominal diameter in US adults, from NHANES 2011–2012.

Panel A: Dysglycemia prevalence ratios by quartiles of sagittal abdominal diameter (SAD), waist circumference (WC) or body mass index (BMI).
Panel B: Prevalence ratios when SAD is considered simultaneously with WC (left side) or with BMI (right side). In age-adjusted models, the relative prevalence of dysglycemia (HbA1c ≥5.7% [≥39 mmol/mol]) is displayed in association with the second (circle), third (triangle), and fourth (square) quartiles (with reference to first quartile) of each indicator. Error bars indicate 95% confidence intervals. a p<0.001; b p<0.01; c p<0.05.

Probability of prevalent dysglycemia estimated by continuous sagittal abdominal diameter, waist circumference or body mass index.
In these age-adjusted plots prepared by restricted cubic splines, the horizontal lines represent the interquartile range (p25 to p75) in the sex-specific population distributions of each adiposity indicator.
