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
backgroundSubarachnoid hemorrhage secondary to a ruptured brain aneurysm should be promptly diagnosed. The angiographic study allows the diagnosis of vascular alterations that determine subarachnoid hemorrhage. The risk of rebleeding is highest in the first 24 h following the first bleeding. The prognosis of the surgical treatment of a brain aneurysm depends on many factors.
objectiveThe aim of the present retrospective study was to determine which prognostic factors are related to the morbidity and mortality of the microsurgical treatment of different brain aneurysms.
methodsA total sample of 371 patients with subarachnoid hemorrhage due to aneurysm bleeding treated by microsurgery from 2013 to 2022 were studied. The variables studied were patient characteristics (age, gender, smoking status, systemic arterial hypertension, and diabetes mellitus), the tomographic findings classified by the Fisher scale, the interval between stroke and surgery, and the clinical condition of patients at admission classified by the Hunt-Hess scale. The primary outcome was the occurrence of death, and the secondary outcomes were the length of hospital stay and the length of stay in the intensive care unit.
resultsThe clinical presentation (characterized by the Hunt-Hess scale) at the time of admission of the patient was an important determining factor in the length of hospital stay and intensive care unit stay and the occurrence of death in these patients. Older age and occurrence of diabetes mellitus were also associated with the outcome of death. The surgical moment characterized by the time between stroke and surgery was inversely associated with the outcome of death.
conclusionThe timing for surgery has to be analyzed concerning the clinical presentation of the patient at the time of admission.
