Factors associated with plasma n-3 and n-6 polyunsaturated fatty acid levels in Tanzanian infants.
Trial report in European journal of clinical nutrition, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
BACKGROUND/
objectivesTo identify factors associated with plasma polyunsaturated fatty acid (PUFA) levels among 3-month-old Tanzanian infants. SUBJECTS/
methodsInfants (n = 238) and mothers (n = 193) randomly selected from participants in the neonatal vitamin A supplementation randomized controlled trial. A cross-sectional study of maternal-infant pairs at 3 months postpartum.
resultsAll infant total, n-3, n-6, and individual PUFA levels were correlated with maternal levels. Infant plasma n-3 PUFA levels were higher when maternal n-3 PUFA levels were higher (mean difference in infant % fatty acid per unit increase in maternal levels ± standard error: 0.79 ± 0.08; P < 0.01). Infant plasma docosahexaenoic acid (DHA) levels were positively associated with maternal DHA levels (0.77 ± 0.09; P < 0.01) but were lower for twin births (-0.55 ± 0.27; P = 0.03). Greater birth weight in kilograms (1.00 ± 0.43; P = 0.02) and higher maternal n-6 PUFA levels (0.20 ± 0.07; P < 0.01) were positively associated with higher infant n-6 PUFA levels, whereas maternal mono-unsaturated fatty acid (MUFA) levels (-0.26 ± 0.08; P < 0.01), maternal mid upper arm circumference (MUAC) (-0.22 ± 0.11; P = 0.04), and male sex (-0.99 ± 0.45; P = 0.03) were associated with lower infant plasma n-6 PUFA levels. Infant plasma arachidonic acid (AA) levels were positively associated with maternal plasma AA levels (0.38 ± 0.09; P < 0.01), but inversely associated with twin births (-1.37 ± 0.67; P = 0.04).
conclusionsGreater birth weight and higher maternal plasma PUFA levels at 3 months postpartum were significantly associated with higher infant plasma PUFA levels at 3 months age. Twin births, male sex, and higher maternal MUFA levels were associated with lower infant plasma PUFA levels. Nutrition counseling for optimal intake of PUFA-rich foods, to lactating mothers in resource-limited settings may be beneficial for improved infant health.
