Table 3 Sensitivity, specificity, positive and negative predictive values for OME group
From: A retrospective study of two populations to test a simple rule for spirometry
| Â | Sensitivity (%) | Specificity (%) | Positive predictive value (%) | Negative predictive value (%) | Disease prevalence (%) | Positive Likelihood Ratio | Negative Likelihood Ratio |
|---|---|---|---|---|---|---|---|
For obstruction | 85 (84–88) | 41 (39–43) | 40 (38–42) | 86 (84–89) | 31 (30–33) | 1.45 (1.39–1.52) | 0.34 (0.29–0.41) |
For any spirometry abnormality (obstruction + restriction) | 77 (75–79) | 50 (47–53) | 74 (72–80) | 55 (51–58) | 65 (63–66) | 1.55 (1.45–1.65) | 0.45 (0.41–0.50) |
