Impact of Different Pneumoperitoneum Pressures on Internal Carotid Artery Blood Flow and Cerebral Oxygenation in Laparoscopic Sleeve Gastrectomy.
Trial report in Obesity surgery, 2026. 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
backgroundHigh intra-abdominal pressure (IAP) during bariatric surgery may compromise cerebral perfusion. This study evaluates the impact of 12 vs. 16 mmHg pneumoperitoneum on internal carotid artery (ICA) hemodynamics and cerebral oxygenation (rSO
methodsIn this prospective, randomized, double-blind study, 67 patients undergoing LSG were allocated into two groups: Group 12 (12 mmHg, n = 34) and Group 16 (16 mmHg, n = 33). Internal carotid artery velocity-time integral (VTI), internal carotid artery blood flow (ICABF), and rSO
resultsSystemic hemodynamics remained stable across groups (P > 0.05). However, Group 16 showed significantly greater cumulative reductions in both ICA-VTI and ICABF compared to Group 12, particularly during the T
conclusionElevated 16 mmHg IAP exerts a subclinical hemodynamic burden by straining cerebral reserves through cumulative ICABF reduction and acute rSO
