Figure 1.
Early survival probability after TIA in patients with positive or negative DWI stratified by statin dosage during hospitalization at 90 days. High-intensity statin therapy could decrease 90-day stroke risk of DWI-positive TIA patients (log-rank = 9.177, p = 0.002). On the contrary, the stroke risk showed no significant difference between HST and non-HST groups in the DWI-negative TIA patients (log-rank = 1.346, p = 0.246).
