A randomised trial comparing 80% and 100% inspired oxygen concentrations for time to adequate preoxygenation using end-tidal oxygen concentration targets.
Article in Indian journal of anaesthesia, 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
Background and Aims: Preoxygenation with 100% oxygen is associated with absorption atelectasis. This study compared 80% and 100% fractional inspired oxygen concentration (FiO Methods: Two-hundred patients for general anaesthesia were randomly divided into either Group I or Group S, the intervention and the standard practice groups, and were preoxygenated with 80% and 100% FiO Results: The median preoxygenation time was comparable between groups: 95 s [interquartile range (IQR) 70-133] and 99.5 s (IQR 80.3-140) in Group I and S, respectively ( Conclusion: Non-inferiority of FiO
