Sensitivity, specificity, and predictive values of the proposed criteria for each category

	T score ⩽−1	T score ⩽−2.5	Z score ⩽−1
Sensitivity (%)	75	86	78
Specificity (%)	60	43	36
PPV^2-150 (%)	91	54	45
NPV^2-150(%)	31	79	71

↵2-150 PPV = positive predictive value; NPV = negative predictive value.
