A maternal sweet diet is associated with the gut dysbiosis in the first trimester of pregnancy.
Article in BMC nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 composition of maternal gut phylum in each trimester of pregnancy has been associated with fetal development, separately. Diet is a main effective factor on the gut composition of phylum. However, associations between dietary glycemic index (GI), load (GL) and total antioxidant capacity (TAC) not studied with the gut population of phylum in mothers at the first trimester of pregnancy. MATERIALS AND
methodsNinety healthy pregnant women aged 18-40 yrs, in the first trimester, were participated. Stool samples were gathered in a fasting state. Population of dominant phylum was determined after DNA extraction based on the 16SrRNA expression, as a housekeeping gene. Dietary intake was collected by a validated food frequency questionnaire and dietary indices were computed.
resultsThe Proteobacteria population was significantly higher in the gut of pregnant mothers than the other phylum (p < 0.001). Participants in the highest level of dietary GI had lower Bacteroidetes (p < 0.001) and Actinobacteria (p = 0.04) in their gut compared to the lowest level. Participants in the lowest level of dietary GL had higher Bacteroidetes (p < 0.001) and lower proteobacteria (p = 0.04) in their gut than the highest level. Dietary selenium showed a significant negative effect on the Firmicutes (p = 0.04) and Proteobacteria (p = 0.04), however positively affected the Actinobacteria (p = 0.01) population. Dietary zinc and manganese showed a negative effect on the Firmicutes population (p = 0.01 and p = 0.003). Zinc and vitamin E showed a negative effect on the Proteobacteria population (p = 0.04 and p = 0.03).
conclusionsA maternal diet with high GI and GL have been associated with the gut dysbiosis, however dietary intake of selenium, zinc, manganese and vitamin E act in favor of the intestinal eubiosis in the first trimester of pregnancy.
