1 · What the graph read from it

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.

2 · The registry

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: This study examines the effect of permissive hypercapnia (PH) on cerebral oxygenation (rSO Methods: This retrospective study analyzed data from elderly patients who underwent laparoscopic surgery with PH mechanical ventilation or conventional ventilation (CV) ventilation strategies between 2019 and 2024. The individuals were separated into two groups as stated by the intraoperative anesthesia method, and equal numbers in each group. A total of 550 patients were initially screened for eligibility, of whom 100 were excluded based on predefined criteria. The final analysis included 450 patients, with 225 receiving PH mechanical ventilation (PH group) and 225 receiving conventional ventilation (CV, control group). Postoperative cognitive dysfunction (POCD), postoperative regional cerebral oxygen saturation (rSO Results: Permissive hypercapnia was associated with significantly improved intraoperative cerebral oxygenation (rSO Conclusion: Permissive hypercapnia significantly improves rSO
