Maternal characteristics associated with ovalbumin concentrations in breast milk.

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
backgroundBreast milk ovalbumin concentrations have been measured with considerable inter-individual variation. Body mass index (BMI) and gestational diabetes mellitus (GDM) in humans, and fish oil supplementation in pigs, have been associated with breast milk protein concentrations. This study aimed to identify whether breast milk ovalbumin concentrations are associated with these maternal characteristics.
methodsThis is a secondary analysis of data collected during a randomized trial. Breast milk ovalbumin concentrations were measured in 66 atopic women 2-6 h after consumption of one egg at 2, 4, and 6 weeks of lactation. Associations between ovalbumin concentrations and maternal characteristics (BMI, GDM and fish oil supplementation during pregnancy) were investigated.
resultsParticipants with GDM (n = 6) had higher ovalbumin concentrations at 2 weeks of lactation (median = 0.87 [IQR 0.27-2.17] ng/mL) compared to participants without GDM (n = 60, median = 0.15 [IQR 0.05-0.67] ng/mL; p = .03). Participants who consumed fish oil supplements during pregnancy (n = 16) had higher ovalbumin concentrations at 4 weeks (median = 0.39 [IQR 0.07-1.20] ng/mL) and 6 weeks (median = 0.29 [IQR 0.15-0.86] ng/mL) compared to those who did not (n = 50, median = 0.05 [IQR 0.05-0.44] ng/mL at 4 weeks, p = .01; and 0.05 [IQR 0.05-0.40] ng/mL at 6 weeks, p = .01). Pre-pregnancy BMI was not associated with ovalbumin concentrations.
conclusionsGDM and pregnancy fish oil supplementation were associated with higher breast milk ovalbumin concentrations. Future, larger studies should further investigate associations between these maternal characteristics and breast milk food protein concentrations.
