Table 3 Comparison of two different cut-off points of plasma cell-free DNA for prediction of 90-day mortality
From: Plasma cell-free DNA in patients needing mechanical ventilation
Cut-off point, GE/ml | 12,000 (Saukkonen 2008 [6]) | 16,000 (present study) |
|---|---|---|
Sensitivity | 0.60 (0.53 to 0.68) | 0.53 (0.45 to 0.60) |
Specificity | 0.55 (0.50 to 0.60) | 0.69 (0.65 to 0.74) |
Positive likelihood ratio | 1.33 (1.13 to 1.57) | 1.72 (1.40 to 2.11) |
Odds ratio unadjusted | 1.84 (1.28 to 2.65) | 2.52 (1.31 to 4.83) |
Odds ratio adjusted | 1.39 (0.89 to 2.16) | 2.22 (1.41 to 3.48) |
