Intermediate vs. High Oxygen Saturation Targets in Preterm Infants: A National Cohort Study.
Article in Neonatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionOptimal oxygen saturation targets remain unknown for extremely preterm infants.
methodsCohort analysis of eligible preterm infants born <29 weeks' gestation admitted between 2011 and 2018 to centers submitting data to the Canadian Neonatal Network (CNN) database. Site questionnaires to determine saturation targets, alarm settings, and date of change, allowed assignation of centers to intermediate (88-93%) or high (90-95%) saturation targets. A 6-month washout period was applied to sites which switched targets during the study period. Our primary outcome was survival free of major morbidity. Secondary outcomes were death, necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD), treated retinopathy of prematurity, and evidence of brain injury during admission. Generalized estimating equations were applied to compensate for demographic differences and site practices.
resultsThere were 2,739 infants in the high (mean gestational age [GA] 26 ± 1.6 weeks) and 6,813 infants in the intermediate (mean GA 26.2 ± 1.6 weeks) saturation target group. Survival without morbidity was higher in the intermediate target group (adjusted odds ratio [aOR] 1.59; 95% CI: 1.04, 2.45). There was no difference in mortality between groups (aOR 0.81; 95% CI: 0.59, 1.11), in NEC, treated retinopathy, or brain injury. On subgroup analysis, restricting data to sites which switched targets during the study, intermediate saturation targets were associated with lower rates of BPD (aOR 0.45; 95% CI: 0.28, 0.72).
conclusionFor neonates <29 weeks' gestation, intermediate saturation target was associated with higher odds of survival without major morbidity compared to higher oxygen saturation target.
