  "abstract": "The C-reactive protein–albumin–lymphocyte (CALLY) index reflects systemic inflammation and immune and nutritional status. We investigated whether admission CALLY was associated with early hospital presentation or receipt of intravenous thrombolysis (IVT) in adults with acute ischemic stroke. This single-center retrospective study included 197 adults with acute ischemic stroke admitted between September 2018 and September 2024. All 98 patients who received IVT were included; 99 non-thrombolyzed controls were selected by computer-generated random sampling from a pool constructed using group-level frequency matching. CALLY was calculated as albumin (g/L) × lymphocyte count (×109/L)/[C-reactive protein (mg/L) × 10]. Early presentation was defined as onset-to-door time ≤4.5 hours. Multivariable logistic regression adjusted for age, sex, and National Institutes of Health Stroke Scale (NIHSS) score assessed associations of ln(CALLY) with early presentation and receipt of IVT. Patients who received IVT had higher NIHSS scores (median, 7 vs 1; P < .001) and lower CALLY values (median, 1.37 vs 2.64; P = .050); however, the CALLY difference was not significant after multiplicity correction (q = 0.122). CALLY was inversely correlated with NIHSS score (Spearman ρ = −0.29; P < .001). After adjustment, ln(CALLY) was not associated with receipt of IVT (adjusted odds ratio = 1.34; 95% confidence interval = 0.98–1.82; P = .063). Its borderline association with early presentation (adjusted odds ratio = 1.34; 95% confidence interval = 1.02–1.77; P = .036) was not consistent across sensitivity analyses. CALLY did not differ significantly between early and late presenters (P = .100). Lower CALLY values among patients receiving IVT were largely explained by greater stroke severity. No consistent independent association was found between CALLY and either outcome. These findings do not support using CALLY to guide thrombolytic decision-making.",
