The aim of this population-based follow-up study was to investigate whether the occurrence of TN is associated with a higher risk of developing stroke.Methods: A total of 1453 people with at least three ambulatory visits in 2001 with the principal diagnosis of TN were enrolled in the TN cohort. The non-TN cohort consisted of 5812 age- and sex-matched, randomly sampled subjects without TN. The 2-year stroke-free survival rate between the two groups was compared using the Kaplan-Meier method. The Cox proportional hazards regression model was used to estimate the hazard ratio of stroke after adjustment for demographic and clinical covariates.Results: In the TN cohort, 73 patients developed stroke during follow-up, while in the non-TN cohort, 157 subjects suffered a stroke. The crude hazard ratio of stroke for the subjects with TN was 1.86 (95% CI, 1.41-2.45; p-<-0.0001). The adjusted hazard ratio was 1.76 (95% CI, 1.33-2.33; p-<-0.0001) after adjusting for demographic characteristics and comorbid medical disorders.Conclusion: This study showed a significantly increased risk of developing stroke after TN. Further studies are needed to investigate the underlying mechanism of this association. ?
