High doses of enteral docosahexaenoic acid omega-3 supplementation for prevention of bronchopulmonary dysplasia in very preterm infants: a protocol for a systematic review and meta-analysis.
Article in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05915806 (Enteral Supplementation With High-dose Docosahexaenoic Acid on the Risk for Bronchopulmonary Dysplasia in Very Preterm Infants), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
introductionDocosahexaenoic acid (DHA) supplementation in the neonatal period has been proposed to prevent bronchopulmonary dysplasia (BPD) in very preterm infants. We aim to determine the effects of an enteral supplementation with high doses of DHA on the risk for BPD at 36 weeks' postmenstrual age (PMA) in very preterm infants born less than 29 weeks' gestation compared with a control. METHODS AND ANALYSIS: We will conduct a systematic review and meta-analysis of randomised controlled trials (RCTs) searching PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, MedRxiv, ClinicalTrials.gov (up to 1 November 2021) as well as reference lists and citations of included articles and previous reviews. RCTs targeting infants born less than 29 weeks' gestation and evaluating the effect of high doses of DHA enteral supplementation in the neonatal period compared with a control will be eligible. Primary outcome will be BPD defined as the need for oxygen and/or ventilation at 36 weeks' PMA. Two authors will independently screen for inclusion, extract data and assess data quality using the Cochrane instrument (risk-of-bias tool 2.0). We will perform meta-analysis using random effects models. Prespecified subgroup analyses are planned for the infant gestational age and sex, the marine source of DHA, mode of administration and duration of exposure. Sensitivity analysis will be performed according to the accuracy of the BPD definition (ie, physiological definition) and according to the risk of bias of the RCTs. ETHICS AND DISSEMINATION: This protocol for a systematic review and meta-analysis does not require ethics approval, as no primary data are collected. This study will assess the effectiveness of high doses of enteral DHA supplementation on BPD and provide evidence to clinicians and families for decision-making. Findings will be disseminated through conferences, media interviews and publications to peer review journals. PROSPERO REGISTRATION NUMBER: CRD42021286705.
