Individuals aged 20 to 53 years with periodontitis in 2001 and 2002 (n\u00a0=\u00a0792,426) and an age\u2010 and sex\u2010matched control group (n\u00a0=\u00a0792,426) were selected. All participants were followed up until TIA diagnosis, 55 years of age, removal from the NHI program, death, or December 31, 2016. The incidence density and hazard ratio (HR) of new\u2010onset TIA were compared between individuals with periodontitis and controls.
