borderline significantp = 0.05
While mortality between the cohorts remained unchanged, the combined stroke/TIA risk converged with the passage of time: at 2 years, the risk was borderline significant (11.2% vs. 6.5%, p = 0.05) [ 16 ], and at 5 years the risk was equivalent between the groups (15.9% vs. 14.7%, p = 0.35) [ 17 ].
