Clinical Characteristics of Contrast Leakage and Contrast-Induced Encephalopathy Following Endovascular Treatment for Unruptured Intracranial Aneurysm.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Contrast-induced encephalopathy (CIE) is a rare but severe complication that can occur following intravascular treatment of intracranial vascular disease. Although CIE is considered a transient neurological disorder, its natural history, pathophysiology, and risk factors are poorly understood. Contrast leakage (CL) is a more frequently observed adverse event than CIE and can lead to CIE. This retrospective study aimed to elucidate the clinical characteristics of CL and CIE and identify the risk factors for each. Methods: We retrospectively reviewed the medical records of 61 patients with unruptured intracranial aneurysms who were treated at our institution between January 2019 and May 2023. Risk factors for CIE and CL were identified by Fisher's exact test for univariate analysis of categorical variables and by unpaired Results: Of the 61 patients, 22 (36%) had CL and 4 (6%) had CIE. Among the clinical characteristics analyzed, older age ( Conclusion: Older age, larger aneurysm, lower serum creatinine, and use of a distal access catheter are risk factors for developing CL, and female sex and greater volume of contrast medium are potential risk factors. No risk factors for developing CIE from CL were identified.
