Method E1: negative = score 0, positive = score 1-3.

Method E2: negative = score 0-1, positive = score 2-3.

Method E3: negative = score 0-2, positive = score 3.

TP = true positive, TN = true negative, FP = false positive, FN = false negative, TOT = total of valid cases, SEN = sensitivity, SPE = specificity, PPV = positive predictive value, NPV = negative predictive value, ACC = accuracy.

Bold values highlight the most important results.
