In the stroke cohort, the interaction patterns were similar, with statistical significance achieved in Models 1 and 3 (Model 1 p=0.043; Model 3 p=0.047) and marginal significance in Model 2 (p=0.063).

In the stroke cohort, interaction significance persisted in Models 1 and 3 (p=0.038 and p=0.040, respectively), but the stratified effect among SI patients did not reach statistical significance (Model 3: HR=0.68, p=0.529), likely reflecting limited statistical power in this smaller subgroup.
