Impact of pre-operative edema index on surgical outcomes in supratentorial meningiomas: A retrospective analysis.
Article in Pakistan journal of medical sciences, 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
Objective: To assess how pre-operative Edema Index (EI) affects surgical outcomes, complications, and hospital stay in patients with supratentorial meningiomas and its role as a predictor for surgical planning and prognosis. Methodology: A retrospective observational study was conducted at the Department of Neurosurgery Unit-II, Punjab Institute of Neurosciences, Lahore, over 14 months (January 2024-February 2025). 31 patients with supratentorial meningiomas were included through non-probability consecutive sampling. Results: Mean age was 41.39 years (range: 18-64 yrs), with male-to-female ratio of 1:1.82. 58.1% (18) were located in the convexity, followed by Parasagittal 12.9% (4), olfactory groove 6.5%(2) , parafalcine 6.5%(2), sphenoid wing 6.5%(2), tuberculum sellae 6.5%(2) and temporal 3.2%(1) regions. Based on size. 3.2% (1) of the tumors were small (<2cm), 35.5% (11) were medium (2-4cm), 38.7% (12) were large (4.1-6 cm) and 22.6% (7) were giant (>6cm). EI was <1 in 38.7% (12), 1-2 in 12.9% (4), and >2 in 32.3% (10); 16.1% (5) had no edema. Higher edema (EI >2) was more common in males (54.5%) than females (20%). Expansion duraplasty was required in 58.1% (18), bone removal in 9.7% (3) and bleeding occured in 6.5% (2). Grade I-II resections were achieved in 90% of patients with EI>2. Neurological deficits occurred in 6 (19.4%). 22.6%(7) had hospital stay exceeding 10 days. Conclusion: Pre-operative EI and tumor location significantly influences surgical complexity, extent of resection, complications, and hospital stay. Incorporating EI into preoperative evaluation can improve surgical planning and outcomes.
