Factors Influencing Breastfeeding Outcomes Following Neonatal Hypoxic Ischaemic Encephalopathy: A Mixed Methods Systematic Review.
Synthesis in Journal of human lactation : official journal of International Lactation Consultant Association, 2026. 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
backgroundHypoxic ischaemic encephalopathy (HIE) is the most frequently occurring neonatal brain injury in term-born infants. Families affected by HIE can face significant breastfeeding and lactation challenges.
aimsThis systematic review aims to improve our understanding of these challenges and identify potential solutions by answering the question: What factors influence breastfeeding and lactation outcomes after neonatal HIE?
methodsThis systematic review used a convergent integrated analysis mixed methods design. Eleven databases were searched for qualitative, quantitative, and mixed methods papers meeting specified criteria (e.g., born ≥ 34 weeks gestation) in November 2022 and again in July 2023 and April 2025. Full methods are registered on PROSPERO https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023375506. Of the 3393 titles and abstracts screened, 455 were identified for full-text screening and 10 were included in the review. An additional seven papers were found via reference lists and citation checking, resulting in a total of 17 included studies.
resultsFive categories of potentially influencing factors were identified: infant medical factors, neuroprotective interventions, feeding during therapeutic hypothermia, support for expressing milk, and parent-infant closeness in the neonatal phase. However, significant evidence gaps were demonstrated, including the influence of environmental and social factors, interventions for lactation support and breastfeeding skills, and qualitative and mixed methods studies specifically focused on breastfeeding and lactation following neonatal HIE.
conclusionCurrent research is insufficient to inform our understanding of factors influencing breastfeeding and lactation outcomes following HIE. High-quality breastfeeding and lactation-specific research is urgently needed to inform information sharing and intervention development for HIE-affected families.
