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

objectiveAssess the relationship between applied face mask force and leak during simulated ventilation using different ventilating devices and mask holds.

designRandomised cross-over simulation study.

settingQuiet, non-clinical room in children's hospital.

participantsTwenty-four experienced neonatal healthcare providers.

interventionsVentilate a manikin for 2 min per trial, each with three trial conditions: self-inflating bag (SIB) with one-hand hold, T-piece with one-hand hold, T-piece with two-hand hold.

main outcome measuresApplied force (newtons (N)) measured under the head and at four locations on the manikin's face (nasal bridge, mentum, left and right zygomatic arches), force asymmetry applied to the mask rim, and mask leak.

resultsUnder-head force was greatest using the SIB with one-hand hold (mean (SD) 20.53 (5.87) N) and least using the T-piece with one-hand hold (mean (SD) 17.58 (6.11) N). While mask leak was reduced with increasing force, leak-free ventilation was achieved by some participants in all trial conditions with low (<10 N) under-head force. Force asymmetry on the manikin's face was similar using a one-hand hold compared with a two-hand hold. With both holds, forces were greater on the side of the face corresponding to the operator's non-dominant hand.

conclusionApplied force and leak varied between devices and mask holds. Force asymmetry was present with both mask holds. Leak-free ventilation could be achieved with small forces using either an SIB or T-piece and either mask hold. Force feedback during training may improve the effectiveness and safety of neonatal ventilation.
