  1. Positive Predictive Value (PPV), Negative Predictive Value (NPV), Positive Likelihood Ratio (+LR), Negative Likelihood Ratio (−LR), 95% Confidence Interval (95% CI), True Positives (TP), False Positives (FP), True Negatives (TN), False Negatives (FN). All values rounded to 2 decimal places.
  2. aStrong diagnostic utility defined as either +LR ≥ 10 or -LR ≤ 0.1 where entire 95% confidence interval satisfies these thresholds. Moderate diagnostic utility defined as +LR > 5 or -LR < 0.2 without satisfying the criteria for strong diagnostic utility.
  3. b10 healthy controls that tested negative with the index test were removed from our calculations.
