Alterations in diaphragmatic activity preceding and during intermittent hypoxaemia events in preterm infants.
Observational study in BMJ paediatrics open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectiveTo assess the activity of the diaphragm using electromyography (dEMG) prior and during apnoea-induced intermittent hypoxaemia (IH) events in preterm infants
designA single-centre observational study.
settingNeonatal intensive care unit. PATIENTS: Preterm infants (<32 weeks of gestation) experiencing IH events with a frequency of >1/hour
methodsHeart rate, oxygen saturation (SpO
results20 infants (gestational age 27.6±1.3 weeks) were included. A total of 591 IH events were used for analysis of which 88 (14.9%), 239 (40.4%) and 264 (44.7%) were scored as central, obstructive and mixed, respectively. In the 1 min before the actual IH, dEMG
conclusiondEMG can detect and characterise central and obstructive apnoea before the IH event occurs, which supports development of automated detection and classification of apnoea events.
