The relationship between prenatal drought exposure and the diversity and composition of gut microbiome in pregnant women and neonates.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Drought induced by climate change poses a serious threat to human health. The gut microbiome also plays a critical role in human health. However, no studies have explored the effect of drought on the human gut microbiome. Therefore, our study aimed to investigate the relationship between drought and gut microbiome. Our study included 59 mothers and 38 neonates in our study. 16S rRNA V3-V4 sequencing was used to profile the gut microbiome. The Standardized Precipitation Evapotranspiration Index (SPEI) was used to represent drought characteristics. KEGG pathway level 3 was employed for functional analysis. Generalized linear models were used to explore the effect of drought on the gut microbiome. Mothers and neonates were divided into the LSPEI (Lower SPEI) group or HSPEI (Higher SPEI) group by calculating the average levels of prenatal SPEI levels. The maternal and neonatal gut microbiome exhibited similar diversities in terms of alpha and beta diversity between the LSPEI and HSPEI groups. However, notable differences were observed in their composition. We found that in the neonatal gut microbiome, Sediminibacterium and Thermovirga were positively associated with SPEI after controlling for PM
