Table 8 Accuracy of colposcopic Lugol’s staining bright yellow in predicting LSIL− (LSIL and normal or benign) and Lugol’s staining mustard yellow in predicting HSIL+ (HSIL and carcinoma)
From: Clinical application of the 2011 IFCPC colposcope terminology
Sensitivity (95% CI) | Specificity (95% CI) | Positive predictive value (95% CI) | Negative predictive value (95% CI) | Youden index | |
|---|---|---|---|---|---|
Lugol’s staining bright yellow/LSIL− | 73.1% (70.5–75.5%) | 47.6% (43.7–51.6%) | 73.5% (71.0–75.92%) | 47.1% (43.2–51.0%) | 0.207 |
Lugol’s staining mustard/HSIL+ | 46.7% (42.8–50.6%) | 83.1% (80.9–85.1%) | 58.1% (53.7–62.4%) | 75.6% (73.2–77.8%) | 0.297 |
