Intra-rater reliability, sensitivity, and specificity of normalized truncated navicular height.

Statistical parameter	NTNH ($n=300$)
ICC (95%CI)	0.98 (0.97–0.99)
SEM	0.005
MDC${}_{95\%}$	0.014
Sensitivity (%)	88.1
Specificity (%)	99.5
AUC (95%CI)	0.98 (0.97–0.99)
Cutoff point	$\le 0.19$

ICC: intra-class correlation coefficient; 95%CI: 95% confidence interval; NTNH: normalized truncated navicular height; SEM: standard error of measurements; MDC${}_{95\%}$: minimal detectable change at 95%CI; AUC: area under the ROC curve.
