A Nomogram Model for Predicting Postherpetic Neuralgia in Patients with Herpes Zoster: A Prospective Study

The incidence of PHN is influenced by factors such as being a woman, being more than 50 years old, having prodromal phase pain, having a large rash area, and having great pain severity during the acute stage. The prediction model developed in this study effectively forecasts the occurrence of PHN using these 5 risk factors, making it a valuable tool for clinical practice.
