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
BACKGROUND AND
objectivesDeep fascia suturing for skull base reconstruction after extended transsphenoidal surgery (eTSS) remains a technically demanding yet essential step, especially in cases with high-flow intraoperative cerebrospinal fluid (CSF) leaks. Although single-hand techniques with concurrent suctioning are standard, we developed a bimanual two-forceps fascia patchwork closure (BM-FPWC) method to enable precise, efficient deep suturing using both hands. This study aimed to describe the BM-FPWC technique and evaluate the operative time and learning curve associated with the procedure through retrospective analysis.
methodsAmong 120 eTSS cases at Toranomon Hospital between June 2024 and January 2025, 34 patients with intraoperative CSF leaks (Esposito grade ≥2) underwent BM-FPWC. Suturing was performed endoscopically using a needle holder and bayonet forceps with both hands, enabled by an endoscope-holding arm. Suturing time and failure rate were compared between earl (n = 17) and late (n = 17) phases to assess the learning curve.
resultsNo postoperative CSF leaks were observed. Mean suturing time was significantly reduced from 58.4 ± 11.1 minutes (early phase) to 44.6 ± 15.8 minutes (late phase,
conclusionBM-FPWC is a safe, efficient, and reproducible technique for skull base reconstruction in eTSS. With experience, the procedure becomes faster and more reliable, suggesting its potential as a standard method for bimanual deep suturing in endonasal skull base surgery.
