A 5-Decade Analysis of Incidence Trends of Ischemic Stroke After Transient Ischemic Attack: A Systematic Review and Meta-analysis

Review (n=206,455 in 68 studies) suggests TIA is linked to high risk of early stroke: 2.4% within 2 days, 3.8% within 7 days, 4.1% within 30 days, and 4.7% within 90 days, though rate of post-TIA stroke might have decreased slightly during past 2 decades.
