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
Resection of large anterior midline skull base meningiomas with extensive peritumoral edema poses high risks due to postoperative edema decompensation leading to increased intracranial pressure. Initial craniectomy prevents intracranial pressure decompensation but requires secondary cranioplasty. This study compares single-stage osteoplastic craniotomy with tumor resection to a two-stage approach using bifrontal craniectomy, tumor resection and subsequent cranioplasty after edema recovery in a second surgical step. Patients with large anterior midline skull base meningiomas (> 50 mm) and extensive peritumoral edema were included. Group 1 underwent single-stage resection (2002-2016), while Group 2 had a two-stage approach (2012-2022). The primary outcome was the Karnofsky Performance Scale (KPS) at three months post-surgery. Secondary outcomes included preoperative KPS, KPS at discharge and last follow-up, ICU stay, hospital stay length and complication rates. A total of 25 patients were analyzed (Group 1: n = 9; Group 2: n = 16). Group 2 demonstrated significantly improved KPS at three months postoperatively (median KPS 70% vs. 50%; p = 0.0204) with a non-significant reduction in ICU stay (10 vs. 6.5 days; p = 0.3284). Although no significant differences were observed in KPS at discharge (Group 1: KPS 30% vs. Group 2: KPS 50%; p = 0.1829) or last follow-up (Group 1: KPS 60% vs. Group 2: KPS 80%; p = 0.1630), Group 2 patients required fewer postoperative interventions for complications unrelated to cranioplasty. Overall complication rates were comparable in both groups (Group 1: 67% vs. Group 2: 56%; p = 0.6274). Two-stage resection of large anterior midline skull base meningiomas with extensive edema provides superior clinical outcomes at three months postoperatively without increasing overall complication rates. These findings support the use of a two-stage surgical strategy for highly selected patients. However, further multicenter studies are warranted to validate these results in larger cohorts.
