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

backgroundRight lateral thoracotomy cardiac surgery induces postoperative atelectasis due to cardiopulmonary bypass (CPB), patient positioning, and mechanical ventilation. Fixed positive end-expiratory pressure (PEEP) may fail to meet pediatric ventilation requirements. This study aims to investigate the effects of driving pressure-guided individualised PEEP on postoperative atelectasis and oxygenation.

methodsChildren aged 6 months to 5 years undergoing right lateral thoracotomy cardiac surgery with CPB were randomly assigned to two groups. Group C received conventional protective ventilation with fixed PEEP of 5 cmH

resultsAt T

conclusionsDriving pressure-guided individualized PEEP ventilation reduces the incidence of postoperative atelectasis in children undergoing right lateral thoracotomy cardiac surgery with CPB. It also improves oxygenation and intraoperative respiratory mechanics. However, there was no significant difference in the incidence of PPCs within 3 days.
