Sensitivity and specificity of the predictive score, HbA1c >7.8% at the admission and the modified score versus the outcome HbA1c >7% one year after the discharge in the testing population

	Score (level 4)	HbA1c >7.8% at admission	Modified score (level 5)
Sensitivity, %	66	69	72
Specificity, %	71	56	71
Positive predictive value, %	81	75	79
Negative predictive value, %	57	56	58

Sensitivity: True positives/(True positives + False negatives); Specificity: True negatives/(True negatives + false positives); Positive predictive value: True positives/(True positives + False positives); Negative predictive value: True negatives/(True negatives + False negatives).
