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

backgroundBubble continuous positive airway pressure (bCPAP) is a low-cost, non-invasive respiratory support therapy for children with respiratory distress, but its effectiveness is dependent on the context. We aimed to understand contextual factors influencing bCPAP implementation for children aged 1-59 months in low-income and middle-income countries (LMICs) and to develop a theory explaining how these factors influence implementation outcomes.

methodsIn this realist review, we generated an initial programme theory comprising candidate context-mechanism-outcome configurations (CMOCs) via review of key references and team discussion. On July 25, 2023, we conducted a search for peer-reviewed and grey literature, without date restrictions, describing bCPAP use for paediatric respiratory distress in LMICs. We included references describing related contexts, mechanisms, or outcomes. We coded statements from the literature supporting each CMOC, iteratively revising and adding CMOCs using inductive and deductive logic. We assembled an international, interdisciplinary panel of 22 bCPAP stakeholders to refine CMOCs using iterative surveys, focus groups, and interviews until we reached thematic saturation. This realist review is registered with PROSPERO (CRD42023403584).

findingsOf 1640 peer-reviewed references and eight grey literature references retrieved, 38 peer-reviewed articles and two grey literature documents were deemed eligible for inclusion after removal of duplicates and screening. After four rounds of expert surveys and three focus groups, we identified 18 CMOCs. CMOCs were synthesised into a final programme theory operating at five levels to influence implementation feasibility, fidelity, and sustainability: (1) the bCPAP device, (2) local partnerships and infrastructure, (3) clinical and technical teams, (4) caregivers and the community, and (5) institutional practices.

interpretationUsing realist methods with a diverse, international stakeholder panel, we generated a theory that could explain how bCPAP therapy works in different contexts. This theory could be leveraged to enhance the rigour of future bCPAP implementation trials.
