From: Recombinant zoster vaccine is associated with a reduced risk of dementia

Incidence of MCI with 95% confidence intervals and adjusted hazard ratios with 95% confidence intervals calculated using a Cox regression model with IPTW are presented for individuals without MCI diagnosis prior to the start of follow-up in comparison of two-dose RZV-vaccinated (n = 64,744) to unvaccinated (n = 258,199) individuals. aAdjusted for time-varying vaccination status (influenza, COVID-19, and other vaccines) besides IPTW. aHR adjusted hazard ratio, CI confidence interval, IPTW inverse probability of treatment weighting, MCI mild cognitive impairment, n number, RZV recombinant zoster vaccine.
