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

objectiveUpdated neonatal resuscitation guidelines for free-flow oxygen administration with a T-piece resuscitator recommend higher gas flow and an open T-piece cap. We aimed to determine the effect of gas inflow rate and cap occlusion on oxygen delivery through a T-piece resuscitator. STUDY

designUsing a NeoPuff™ T-piece, oxygen inflow was randomly adjusted from 4 to 10 liters per minute (LPM). Gas outflow and oxygen concentration were measured with the T-piece cap open and occluded. Data were analyzed with repeated measures 2-way ANOVA.

resultGas outflow was significantly decreased with the T-piece cap open compared with occluded at each inflow rate (p < 0.001). There was no difference in oxygen concentration of the outflow gas.

conclusionGas flow from the T-piece is affected by the inflow rate and cap occlusion but oxygen concentration is not. To deliver 5 LPM of free-flow oxygen with the cap open, a minimum of 8 LPM gas inflow is required.
