Article in Placenta, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03146156 (Lifestyle Intervention in Preparation for Pregnancy), which is not on this map. Cited by 46 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

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.

Abstract

introductionThe fetus is dependent on the placenta for its supply of long chain polyunsaturated fatty acids (LCPUFA), which are essential in fetal growth and development. Previous work suggests that high maternal body mass index (BMI) inhibits fetal LCPUFA delivery and males have greater fatty acid requirements than females during development. We hypothesized that male placental fatty acid uptake would be more sensitive to maternal BMI compared to females.

methodsTerm placental samples were collected from healthy women receiving Cesarean section (n = 38). Placental fatty acid transporter and binding protein gene expression and uptake of oleic acid (OA), arachidonic acid, (AA) and docosahexanoic acid (DHA) were measured. Two-way ANOVA was used to assess the effects of fetal sex and maternal overweight/obesity (BMI >26 kg/m2).

resultsPlacental fatty acid uptake of OA was 43% lower in male offspring and 73% higher in female offspring of obese compared to normal BMI women (P < 0.05). The interaction between fetal sex and maternal BMI had a significant effect on both OA (P = 0.002) and AA uptake (P = 0.01). DHA uptake was not affected by fetal sex or maternal obesity. Placental fatty acid transporter CD36 and binding protein FABP5 gene expression levels were lower in male offspring of obese mothers but were not affected by BMI among females.

conclusionMaternal obesity and fetal sex significantly affect the placental uptake of oleate and arachidonate. Placental fatty acid uptake in both male and female fetuses is sensitive to maternal BMI, but males may have inadequate acquisition of the unsaturated fatty acid OA, when exposed to maternal obesity.
