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

backgroundIn patients with blunt thoracic injury requiring mechanical ventilation lateral positioning is routinely performed. Whether it modifies ventilation distribution and aeration is unclear. STUDY DESIGN AND

methodsPatients receiving pressure support ventilation (PSV) were positioned 30 degrees on each side for 30 min. Electrical impedance tomography (EIT) was used to quantify the percentage of right and left ventilation. Secondary outcomes included right and left tidal volume and the modified lung ultrasound score. At baseline, patients were categorized according to ventilation distribution: symmetrical (right lung receiving 50-55% of total ventilation) or asymmetrical.

resultsTwenty-four patients were included (mean age 51 ± 20 years, 79% male) under median PSV 5 cmH

conclusionIn blunt thoracic injury, lateral positioning during PSV is associated with a modest increase in regional ventilation of the dependent lung, but this effect is limited to patients with symmetrical ventilation distribution and normal compliance. In others, longer duration or higher degree of lateralization may be required.
