Higher Dietary Intake of Animal Protein Foods in Pregnancy Is Associated with Lower Risk of Adverse Birth Outcomes.
Article in The Journal of nutrition, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThe prevalence of adverse birth outcomes is highest in resource-limited settings such as sub-Saharan Africa. Maternal consumption of diets with adequate nutrients during pregnancy may protect against these adverse outcomes.
objectivesThe objective was to determine the association between maternal dietary consumption of animal source foods (ASFs) and the risk of adverse birth outcomes among HIV-negative pregnant women in Tanzania.
methodsUsing dietary intake data from 7564 HIV-negative pregnant women, we used Poisson regression with the empirical variance (generalized estimating equation) to estimate the RR of adverse birth outcomes-preterm birth, very preterm birth, small for gestational age (SGA), low birth weight (LBW), stillbirth, and neonatal death-for higher and lower frequency of ASF intake.
resultsMedian daily dietary intake of animal protein was 17 g (IQR: 1-48 g). Higher frequency of ASF protein intake was associated with lower risk of neonatal death (quartile 4 compared with quartile 1; RR: 0.59; 95% CI: 0.38, 0.90; P-trend = 0.01). Higher fish intake was associated with lower risk of very preterm birth (high tertile compared with low; RR: 0.76; 95% CI: 0.58, 0.99; P-trend = 0.02). Any meat intake was protective of preterm birth (RR: 0.73; 95% CI: 0.65, 0.82; P < 0.001), very preterm birth (P < 0.001), LBW (P < 0.001), and neonatal death (P = 0.01) but was associated with increased risk of SGA (RR:1.19; 95% CI: 1.01, 1.36; P = 0.04). Any egg intake was protective of very preterm birth (RR: 0.50; 95% CI: 0.31, 0.83; P = 0.01) as compared with no egg intake. Finally, any dairy intake was associated with lower risk of preterm birth (RR: 0.82; 95% CI: 0.68, 0.98; P = 0.03) and very preterm birth (RR: 0.53; 95% CI: 0.34, 0.84; P = 0.01).
conclusionsHigher frequency of dietary intake of ASF is associated with lower risk of adverse birth outcomes in urban Tanzania. Promoting prenatal dietary intake of ASF may improve birth outcomes in this region and similar resource-limited settings.
