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: Reduced internal carotid artery (ICA) blood flow can cause cerebral hypoperfusion, increasing the risk of intraoperative or postoperative cerebral ischemia. In laparoscopic surgery, postural changes and pneumoperitoneum may further compromise ICA hemodynamics. This study aims to evaluate the effects of intraoperative postural transitions on ICA blood flow in patients undergoing gynecologic laparoscopic surgery. Methods: A single-center, prospective, non-randomized observational study was performed. Measurements of ICA blood flow, heart rate (HR), and mean arterial pressure (MAP) were obtained at eight intraoperative time points: upon arrival to the operating table while awake (T1), post-induction of anesthesia in the supine position (T2), following pneumoperitoneum in the supine position (T3), immediately after placement in the Trendelenburg position (T4), 10 minutes (T5) and 20 minutes (T6) after Trendelenburg positioning, upon return to the supine position (T7), and at the conclusion of surgery (T8). Results: A total of 79 patients were enrolled in this study. A significant reduction in ICA blood flow was observed at T2 compared to T1 (263.8 ± 11.4 vs 323.5 ± 12.0 mL/min, Conclusion: Intraoperative postural transitions during gynecologic laparoscopic surgery are associated with fluctuations in ICA blood flow. The return from the Trendelenburg to the supine position results in a marked decrease in ICA blood flow, HR, and MAP.
