The Cox proportional-hazards model based on baseline levels of vitamin B5, B6, and B9 to predict miscarriage risk. Note (A) Survival curve at mean baseline level of vitamin B5, B6, and B9, which cumulative RSA risks was 3.5% at 23 gestational weeks; (B) ROC curve of OSA vs. NFP, with sensitivity of 95.2% and specificity of 39.0% when maximum prediction accuracy; (C) ROC curve of CSA vs. NFP, with sensitivity of 92.3% and specificity of 60.6% when maximum prediction accuracy. NFP, normal first pregnancy; OSA, once spontaneous abortions; CSA, continuous spontaneous abortions.
