Abdominal Caliper

The Holtain-Kahn Abdominal Caliper’s inbuilt spirit level (which ensures a vertical measurement is taken) has helped to give estimates of intraobserver precision which produced a mean of absolute deviation of 0.4cm, the coefficient of variation of 2.5% and an intraclass correlation coefficient of 95.8.

The sagittal abdominal diameter has been shown to be highly correlated with the volume of visceral fat.
