Current Evidence of the Effect of Breastfeeding on Ear Molding Outcomes: A Scoping Review.
Article in The Laryngoscope, 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
objectiveTo provide an overview on auricular molding and to investigate whether breastfeeding is associated with greater cartilage malleability or improved perinatal auricular molding outcomes. DATA SOURCES: Embase, MEDLINE, and CENTRAL databases.
methodsThree databases were comprehensively searched for treatment of congenital auricular malformations or deformations with auricular molding. Extracted data included study design, patient demographics and auricular anomalies, interventions and outcomes measures, and references to the effect of estrogen and breastfeeding on cartilage malleability and ear molding.
resultsOut of 1018 unique articles, 67 were included in this review. The articles included a total of 3645 patients and 5384 ears, of which helical rim abnormality (20.6%), lop/lidding/cup ear (20.2%), and prominent ear (11.1%) were the most represented. Of the 67 articles referencing estrogen levels, 49 supported the claim that estrogen increases auricular cartilage malleability. Fifteen articles (22.4%) referenced the effect of breastfeeding on infant circulating estrogen levels and molding outcomes, while 8 (53.3%) of those articles supported the claim. Notably, only 4 primary sources were referenced regarding the effect of breastfeeding among all reviewed literature.
conclusionsThere is insufficient evidence to suggest that breastfeeding leads to increased circulating estrogen levels in infants, increased auricular cartilage malleability, or improved ear molding outcomes. The direct impact of hyaluronic acid on the mechanical properties of auricular cartilage in vivo remains unclear.
