rIAs, ruptured intracranial aneurysms; uIAs, unruptured intracranial aneurysms; NLR, neutrophil-lymphocyte ratio; and DCI, delayed cerebral ischemia; CI, confidence interval; OR, odds ratio.

*Model 1: adjusted for age and sex.

†Model 2:

Size: adjusted for model 1+ history of stroke, hypertension, hyperlipidemia, diabetes mellitus, heart disease, smoking status, and aneurysm location.

Aneurysm rupture: adjusted for model 1+ history of stroke, hypertension, hyperlipidemia, diabetes mellitus, heart disease, smoking status, aneurysm location, and aneurysm size.

Poor outcome: adjusted for model 1+ history of stroke, hypertension, hyperlipidemia, diabetes mellitus, heart disease, smoking status, aneurysm location, aneurysm size, treatment modality, and modified Fisher grade.

DCI: adjusted for model 1+ history of stroke, hypertension, hyperlipidemia, diabetes mellitus, heart disease, smoking status, aneurysm location, aneurysm size, treatment modality, and modified Fisher grade.
