Maternal macronutrient intake at pregnancy and offspring growth trajectory through childhood: a prospective analysis in the Growing Up Today Study 2 cohort.

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
backgroundChildhood obesity has become a public health challenge globally. Existing studies have indicated a potential link between maternal dietary macronutrient compositions and subsequent weight changes in their offspring during early childhood, although few studies have been conducted through early adulthood.
objectivesWe aimed to investigate the relationship between maternal macronutrient intake before or during pregnancy and offspring body weight from late childhood till early adulthood.
methodsWe included 5715 children from the Growing Up Today Study 2 (GUTS2) (mean 11.8 y old at baseline in 2004) born to 4731 mothers who participated in the Nurses' Health Study II (NHSII) during 1989-1995. Diet during or before pregnancy was assessed using a validated food frequency questionnaire (FFQ) in 1991 and 1995. Age- and sex-specific body mass index (BMI) were used to define overweight and obesity in childhood and adolescence. Multivariable linear and log-binomial regression models with generalized estimating equations were used to evaluate the associations of interest.
resultsThe mean (SD) maternal macronutrient percent energy intake during pregnancy was 19.3% (3.1) for protein, 51.2% (6.6) for carbohydrates, and 30.8% (5.0) for total fat. For diet during pregnancy, after multivariate adjustment for maternal and offspring risk factors, compared with the lowest quartile, the highest quartile of trans fatty acid consumption was associated with a 0.20 unit (95% confidence interval [CI]: 0.00, 0.40) increase in BMI z-score without a significant linear trend (P-trend = 0.06). A positive association with BMI z-score was also observed for total fat intake (β: 0.21; 95% CI: 0.05, 0.36; P-trend = 0.02) when replacing total carbohydrate, and vice versa (β: -0.24; 95% CI: -0.40, -0.08; P-trend = 0.02 for total carbohydrate intake). For diet before pregnancy, none of the macronutrients were associated with offspring BMI z-score or the risk of overweight or obesity.
conclusionsHigher fat, especially trans fat intake, during pregnancy was positively associated with higher body weight among offspring. Other macronutrients from various food sources were not associated with the offspring weight. Overall, these data suggest that, apart from trans fatty acids, other macronutrient composition of maternal diet may have minimal impact on offspring body weight in this well-nourished population.
