Endovascular coiling vs. surgical clipping for ruptured intracranial aneurysms: an in-hospital outcome win ratio analysis from a Colombian tertiary center

In this Colombian cohort, hierarchical outcome analysis suggested superior in-hospital outcomes for endovascular coiling vs. surgical clipping. However, the substantial attenuation of this association in adjusted analyses indicates that these apparent advantages may largely reflect case selection patterns rather than inherent treatment superiority, as residual confounding by aneurysm complexity cannot be excluded.
