Key result
Prediction equations based on eight clinical factors reliably estimated the absolute 5-year risk of serious vascular events in TIA patients, but lacked precision for high-risk discrimination.
Why the study?
Can prediction equations based on clinical prognostic factors accurately predict the five-year risk of serious vascular events in patients with transient ischaemic attacks?
Cohort (n=2,229)
Yes
Can prediction equations based on clinical prognostic factors accurately predict the five-year risk of serious vascular events in patients with transient ischaemic attacks?
Prediction equations can reliably estimate the absolute five-year risk of serious vascular events in TIA patients at low risk, but lack precision for distinguishing high-risk patients.

May inform low-risk TIA decisions; leaves open refined models for high-risk discrimination in prospective cohorts.
Hankey et al. (1993) conducted a cohort in Transient ischaemic attacks (TIAs) (n=2,229). Prediction equations based on eight clinical prognostic factors was evaluated on Serious vascular event at five years. Prediction equations based on eight clinical factors reliably estimated the absolute 5-year risk of serious vascular events in TIA patients, but lacked precision for high-risk discrimination.
