Low vs. High Inspiratory Oxygen Fraction During Mechanical Ventilation in Obese Patients: Impact on Postoperative Pulmonary Outcomes.
Article in Anesthesiology research and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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: Obese patients undergoing general anesthesia are at heightened risk for postoperative pulmonary complications (PPCs) due to impaired respiratory mechanics. While lung-protective ventilation strategies are widely adopted, the role of intraoperative inspiratory oxygen fraction (FiO Methods: We conducted a prospective, randomized controlled trial comparing low (FiO Results: The incidence of PPCs was 70.7% in the high FiO Conclusion: Although the difference was not statistically significant, the observed lower incidence of PPCs in the low FiO
