↵* For all comparisons (using χ

^{2}tests to compare cases and matched controls and to compare stroke and TIA subgroups),*p*< 0.001, except for the comparison of stroke versus TIA subgroups for MI outcomes, where*p*> 0.05 at all follow-up time points.↵† The percentages for longitudinal analyses are based on the denominator of subcohorts with complete 1-, 3- or 5-year follow-up. The denominator at 1 year was the same as the full cohort: 26 366 total (15 950 with stroke and 10 416 with TIA). At 3 years, the subcohort denominator was 21 548 total (13 287 with stroke and 8261 with TIA), and at 5 years the subcohort denominator was 15 571 total (9894 with stroke and 5677 with TIA). All matched control cohorts were matched 10:1 with cases, so the denominator for the matched control cohort was 10 times the total denominator for each year: 263 660 at 1 year, 215 480 at 3 years and 155 710 at 5 years.
