Risk factors for poor prognosis in patients with zoster-associated neuralgia who underwent interventional pain management

Age ≥ 65 years (odds ratio, 2.985; 95% confidence interval, 1.449-6.148; <i>p</i> = 0.003), disease duration >3 months (odds ratio, 3.135; 95% confidence interval, 1.685-5.832; <i>p</i> < 0.001), head and face pain (odds ratio, 3.140; 95% confidence interval, 1.557-6.330; <i>p</i> = 0.001), immunosuppressants use (odds ratio, 2.737; 95% confidence interval, 1.168-6.416; <i>p</i> = 0.021), higher NLR (odds ratio, 1.454; 95% confidence interval, 1.233-1.715; <i>p</i> < 0.001), PRF (odds ratio, 2.324; 95% confidence interval, 1.116-4.844; <i>p</i> = 0.024) and RF-TC (odds ratio, 5.028; 95% confidence interval, 2.139-11.820; <i>p</i> < 0.001) were identified as independent risk factors for poor prognosis in patients with ZAN who underwent interventional pain management.
