OC14.03: Assessment of the head circumference to maternal height ratio close to delivery: any role in the screening of labour dystocia?

Abstract

Oral communication abstractsResults: Simple Rules had a sensitivity of 92% and specificity of 90.6% while classifying adnexal masses. As per original cut-off value of 10% ADNEX model had an AUC of 0.932 (0.858-1), with a sensitivity of 92% (74-99) and specificity of 87.5% (77-94). For polytomous classification, ADNEX model had the best performance at differentiating benign from advanced (stage II-IV) primary tumours. At cut-off 10%, LR1 had an AUC of 0.878 (0.719-1), sensitivity of 88% (69-97), specificity of 93.8% (85-98) and LR2 had an AUC of 0.960 (0.92-0.999), with a sensitivity of 84% (64-95) and specificity of 93.8% (85-98). At original cut-off value of 200 for RMI 3, AUC was 0.941 (0.888-0.993), with a sensitivity of 68% (46-85) and specificity of 93.8% (85-98). Conclusions: ADNEX model and LR2 have a great potential and highly promising results to modify the conventional management protocol for adnexal masses. The polytomous classification proposed in the ADNEX model is first of its kind. It could be used as an initial screening tool by examiners with limited expertise in ultrasonography.
