Table 2 Summary estimates for sensitivity, specificity and positive and negative likelihood ratios from the bivariate model.

From: A systematic review of tests for lymph node status in primary endometrial cancer

Index test Mean sensitivity (95%CI) Mean specificity (95%CI) Positive likelihood ratio (95% CI) Negative likelihood ratio (95% CI)
Sentinel Node (SN) 0.79 (0.58 to 0.91) 0.96 (0.89 to 0.99) 18.88 (6.70 to 53.24) 0.22 (0.10 to 0.48)
CT scan 0.45 (0.28 to 0.64) 0.88 (0.78 to 0.94) 3.81 (2.00 to 7.28) 0.62 (0.45 to 0.86)
MRI 0.72 (0.55 to 0.85) 0.97 (0.93 to 0.99) 26.72 (10.56 to 67.64) 0.29 (0.17 to 0.49)
  1. Sensitivity: p-value SN vs CT = 0.018, p-value SN vs MRI = 0.546, p-value CT vs MRI = 0.039.
  2. Specificity: p-value SN vs CT = 0.095, p-value SN vs MRI = 0.546, p-value CT vs MRI = 0.014
