This study aimed to investigate whether herpes zoster may serve as a clinical marker of previously unrecognized T2DM among people aged 65\u201384 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective cohort study using de-identified electronic health records from TriNetX (2006\u201324). Patients aged 65\u201384 years with a diagnosis of herpes zoster (ICD-10 code B02) were compared with age-matched patients without herpes zoster. Propensity score matching was applied to balance baseline characteristics. The primary outcome was newly diagnosed T2DM. Hazard ratios and 95% confidence intervals were estimated using Cox proportional hazards models within the TriNetX platform.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After propensity score matching and exclusion of patients who developed the outcome prior to the predefined follow-up window, 16 175 herpes zoster patients and 16 336 matched controls were included. During 1 year of follow-up, the cumulative incidence of T2DM was 2.362% in the herpes zoster group and 0.343% in controls. Herpes zoster was associated with a significantly higher likelihood of newly diagnosed T2DM (hazard ratio, 6.517; 95% confidence interval, 4.923\u20138.627).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Herpes zoster was associated with newly diagnosed T2DM in older people.
