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

backgroundThe effect of different fresh gas flow (FGF) on achieving the target expired oxygenation (FeO

methodsOne hundred adult patients aged 18-60 years and with American Society of Anesthesiologists' physical status I-III were randomized to receive optimal FGF (=MV+500 mL) or excess FGF (i.e., +50%) for pre-intubation oxygenation targeted to FeO

resultsBoth optimal and excess FGF groups showed similar efficacy in achieving FeO

conclusionPre-intubation oxygenation using the optimal FGF is non-inferior to excess FGF, and is as adequate as using excess FGF to achieve FeO
