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: Hemorrhage originating from the intercavernous sinuses during transsphenoidal approaches for skull base injury is a common occurrence, but it can be easily controlled. However, in specific cases, it may necessitate suspending the surgery or result in hemodynamic instability. Case Description: We present the case of a 7-year-old female patient who underwent transsphenoidal endoscopic endonasal for craniopharyngioma resection. The patient's parents gave consent for the procedure. During the procedure, significant intraoperative bleeding occurred, which was necessary to stop the resection. After the surgery, cerebral angiography was performed, which identified a prominent anterior intercavernous venous sinus as the source of the bleeding. A successful embolization using onyx was performed, leading to a satisfactory postoperative recovery without any complications. The patient then underwent a second surgical intervention for the resection of the craniopharyngioma through an endoscopic endonasal transsphenoidal approach. This procedure achieved a complete resection of the lesion without complications, and the patient experienced an adequate postoperative recovery. Conclusion: The objective of this case is to describe a previously unreported technique involving onyx embolization for controlling prominent bleeding from the intercavernous sinus and as a presurgical embolization method to reduce the risk of bleeding during endoscopic endonasal surgery for resection of a craniopharyngioma.
