A nomogram for predicting prognostic risk factors in individuals with poor grade aneurysmal subarachnoid hemorrhage: a retrospective study.
Article in Neurosurgical review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Poor-grade aneurysmal subarachnoid hemorrhage (PGASAH) is associated with high mortality and morbidity despite advanced treatments. Accurate prediction of prognosis remains a clinical challenge. This study aimed to identify independent risk factors and develop a predictive nomogram for unfavorable outcomes in PGASAH patients. This retrospective study included 348 PGASAH patients treated between 2003 and 2016. Univariate and multivariate logistic regression analyses were performed to evaluate the association of premorbid conditions, admission aSAH clinical parameters, admission laboratory parameters, and clinical complications with unfavorable outcomes, defined as mRS > 2 at 6 months. Independent predictors were identified, and a nomogram was constructed to assess predictive accuracy and clinical utility. The median age of PGASAH patients was 55.1 years, 64.9% were females. Independent predictors of unfavorable outcomes (mRS > 2) at 6 months included age > 55 years (aOR = 2.44), cardiac valve disease (aOR = 6.50), dilated pupils at admission (aOR = 2.64), early infarction (aOR = 5.56), and delayed cerebral ischemia (aOR = 5.09). The nomogram demonstrated good predictive performance with an AUC of 0.807. Decision curve analysis affirmed its clinical applicability. The intuitive nomogram helps physicians predict PGASAH prognosis at discharge, improving long-term management, optimizing resource allocation, and enhancing patient and family awareness and psychological preparedness. External validation is required for broader clinical use.
