Table 4 Correlation between radiological size of the largest lymph node per station and sensitivity, specificity, predictive value, accuracy, and likelihood ratio
From: Preoperative multidetector-row computed tomography scan staging for lymphatic gastric cancer spread
Lymph nodes | Radiologically detected | Pathologically infiltrated | Sensitivity | Specificity | PPV | NPV | Accuracy | LR (95% CI) |

All radiologically detected lymph nodes | 382 | 145 | 70.7 | 45.8 | 37.9 | 77 | 53.8 | 1.30 (1.15 to 1.47) |
