Predicting neurological complications post clipping surgery in unruptured intracranial aneurysms using the NEURO score: a multi-center retrospective cohort study.
Observational study in Korean journal of anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPredicting fatal neurological complications after clipping surgery for unruptured intracranial aneurysms (UIAs) is crucial; however, existing scoring systems are limited by narrow consideration of factors. We aimed to develop and validate a comprehensive risk stratification scoring system that incorporates patient-, aneurysm-, and operation-specific variables for predicting postoperative neurological complications in UIA surgeries.
methodsThis multi-center retrospective cohort study was conducted from September 2018 to October 2023. Patients undergoing clipping surgery for UIAs were divided into development and validation sets based on the treating institution. A predictive score for postoperative neurological complications was developed from a multivariate logistic regression analysis. The score, named NEURO, that incorporates variables like previous neurological disease, categorized aneurysm location and size, categorized operation time, and transfusion was validated externally.
resultsThe study included 2847 patients, with 1547 and 1300 in the development and validation sets, based on the institution of surgery, respectively. The incidence of neurological complications was 5.7% (88/1547) and 5.6% (73/1300) in the development and validation sets, respectively. The NEURO score showed good predictive ability with C-statistics of 0.720 (95% CI [0.667-0.776]) in the development set and 0.693 (95% CI [0.631-0.754]) in the validation set, demonstrating good calibration across the predicted probability range.
conclusionsThe NEURO score, integrating multiple perioperative variables, may effectively predict the risk of neurological complications post UIA clipping surgery, aiding in identifying high-risk patients. This tool could enhance clinical decision-making and patient management in neurosurgical practice.
