From: Identifying older diabetic patients at risk of poor glycemic control

  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
  1. 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).
