Impact of surgery within 6 hours on preoperative rerupture and prognosis of poor-grade aneurysmal subarachnoid hemorrhage.

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: Preoperative rerupture is a major cause of poor outcome in poor-grade aneurysmal subarachnoid hemorrhage (PaSAH). The optimal surgical timing is controversial. This study aims to investigate the effect of surgery within 6 h on preoperative rerupture and the prognosis of PaSAH. Methods: A retrospective study was performed on 140 PaSAH patients treated at the Neurosurgery Department of the 904th Hospital of the Joint Logistics Support Force between July 2017 and July 2025, with a 6-month postoperative follow-up. Patients were divided into two groups: the surgery within 6 h group and the surgery beyond 6 h group, based on the time from aneurysm rupture to surgery. Results: Of the 140 patients, 83 (59.3%) were in the surgery within 6 h group, and 57 (40.7%) were in the surgery beyond 6 h group. The surgery within 6 h group had significantly higher proportions of H-H classification, mFisher classification, and decompressive flap use, while the proportion of acute hydrocephalus was notably lower, with statistically significant differences ( Conclusion: Surgery within 6 h effectively reduces the risk of preoperative rerupture in PaSAH patients and significantly improves long-term outcomes.
