From: Histological diagnostic criterion for chronic endometritis based on the clinical outcome
A receiver operating characteristic curve of the non-CE group for live birth. The sensitivity and specificity of the non-CE group for live birth were calculated for each of these diagnostic criteria, and a receiver operating characteristic (ROC) curve was drawn. The area under the curve of the ROC curve was 0.785. The optimal cut-off value was obtained when ≥ 1 plasma cell was found in 10 HPFs (sensitivity of 87.5% and specificity of 64.9%)
