Trial report in British journal of anaesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05672329 (Functional Residual Capacity Under Apnoeic Oxygenation with Different Flow Rates in Children), which is not on this map. Not yet cited in PubMed.

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.

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.

Abstract

backgroundLung atelectasis is a well-recognised consequence of general anaesthesia in children and can cause poor oxygenation. Lung recruitment manoeuvre has been proposed as a strategy to counteract atelectasis. In this feasibility study, we evaluated whether a recruitment manoeuvre in children with a supraglottic airway restores end-expiratory lung volume (EELV) to baseline using electrical impedance tomography.

methodsAfter ethics committee approval (BASEC 2022-01833), we included children (ASA physical status 1-2, 10-20 kg) scheduled for anaesthesia with a supraglottic airway. We performed a recruitment manoeuvre by setting an anaesthesia machine to spontaneous breathing with a 3 L min

resultsOf the 95 eligible children, we analysed 74 datasets. The median (95% confidence interval) estimated difference in EELV after recruitment manoeuvre vs baseline was -0.9 ml kg

conclusionsIn children undergoing general anaesthesia with the use of a supraglottic airway, a recruitment manoeuvre effectively restores EELV to baseline. CLINICAL
