Exposure group
Reference group
Montelukast claim is used as the exposure group.
Fluticasone claim is used as the reference group.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
This study will employ a new user, active comparator, observational cohort study design comparing Montelukast versus Fluticasone. The patients will be required to have continuous enrollment during the baseline period of 365 days before initiation of study drugs (cohort entry/index date). Follow-up for the outcome (dementia) differs between analyses. Follow-up begins the day after drug initiation (analysis 1, 3, 4); 180 days after drug initiation (analysis 2).
