A nomogram predicting the risk of CID in CVT patients. Risk factors, including PNI scores and gender were assigned corresponding scores on the points axis, and the total points was calculated by adding the corresponding scores of all risk factors. The probability of CID in each patient can be obtained through the CID axis relative to total points axis. Abbreviations: CVT, thrombosis of dural sinuses and/or cerebral veins; PNI, prognostic nutritional index; CID, cerebral intraparenchymal damage
