Of 2,540 patients ascertained with probable or definite strokes between 2002 and 2017, 48 (1.9%) were excluded from the main analysis because of incomplete data on medical history or NIHSS, mainly due to early death, nonhospitalization, or limitations due to end-of-life care (eFigure 1, Baseline Characteristics and Subtype in 2,492 First-in-Study Stroke Patients, Both in the Overall Cohort and Stratified by Prestroke Multimorbidity LevelDistribution of Individual Comorbidities Across Unweighted CCI Categories in 2,492 Patients With a First-in-Study Period StrokeOf patients with ≥2 CCI comorbidities, 375 (53.5%) had a premorbid mRS ≥2 (The proportion of intracerebral hemorrhage (ICH) vs ischemic stroke was lower in patients with multimorbidity (aOR/CCI comorbidity 0.80, 0.70–0.92, The CCI was crudely associated with increased NIHSS at 24 hours (OR per CCI comorbidity 1.11, 95% CI 1.01–1.23 for NIHSS 5–9 vs 0–4; 1.12, 1.03–1.21 for NIHSS ≥10 vs 0–4; linear regression using weighted CCI and NIHSS: β = 0.24, However, CCI differed across TOAST subtypes of ischemic stroke (
