Variables without significant differences (p > 0.05) were ASPECTS, CBV index, ischemic core volume, penumbra volume, mismatch ratio, NIHSS, creatinine, BUN, UA, PT, FIB, CRP, LYM, NEUT, PLT, HbA1c, sex, first-pass effect, thrombolysis, smoking, hypertension, atrial fibrillation, diabetes mellitus and time metrics (onset-to-door time, onset-to-puncture time, door-to-puncture time, puncture-to-recanalization time, onset-to-recanalization time) (Table 3). This evidence concerns the gene CRP and atrial fibrillation.
