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
The aim of this study was to determine if the dietary pattern of pregnant women has any compensatory effect on the fatty acid desaturase (FADS) gene expression, thus enhancing the conversion of precursors to long chain polyunsaturated fatty acids (LCPUFA) to spare the overall LCPUFA levels. The dietary intake of plant-based precursor polyunsaturated fatty acids (PUFA) influences circulating levels of LCPUFA. We hypothesized that low LCPUFA diets during pregnancy would compensate by higher expression of FADS genes to enhance the conversion of precursors to LCPUFA to spare the overall LCPUFA levels. Seventy-five pregnant women were enrolled during the last trimester of pregnancy based on the eligibility and exclusion criteria. Maternal LCPUFA in plasma, expression of FADS1 and FADS2 genes, FADS2 Indel genotype status and neonate birth weight were studied.In the vegetarian group (n = 25), plasma α-linolenic acid (ALA) but not linoleic acid (LA) was significantly lower (p < 0.05) than the non-vegetarian group (n = 50). No significant differences were found for arachidonic acid (AA) or docosahexaenoic acid (DHA) levels. FADS1 expression was significantly higher in the vegetarian group compared to the non-vegetarian group. There was no significant difference in the birth weight of the neonates between two groups. No significant correlation was observed between FADS2 Indel genotype and birth weight. Our small sample size study demonstrated an increase FADS1expression during pregnancy in vegetarian pregnant women that may have contributed to the maintenance of AA, eicosapentaenoic acid and DHA levels thereby ensuring that the overall LCPUFA levels of the neonate is not compromised.
