Univariable and multivariable logistic regression analyses of leptomeningeal collaterals for intracranial atherosclerosis-related large vessel occlusion (ICAS-LVO). Odds ratios with 95% confidence intervals from (A) univariable and (B) multivariable logistic regression analyses are plotted. In multivariable analyses, each leptomeningeal collateral assessment method was adjusted by current smoking, atrial fibrillation, and initial NIHSS score.
