ROC curve for the screening of PPD by EPDS scale. Receiver operating characteristic curve for the EPDS screening test, demonstrating area under curve at chosen cutoff level i.e. (12/13). The area under curve was 0.982. Thus the Nepalese version of EPDS had accuracy of 98.2 % (95 % CI 0.970–0.994, p = 0.001) in screening for cases of PPD with the cutoff at 12/13. Hence, this cut off level can be considered optimum to define threshold level for depressive symptoms
