Stool microbial composition is associated with recent and future diarrhea and fever events in breastfed Danish infants.

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
Gastroenteritis is an important cause of ailment among infants in high-income countries, including Denmark. There are many cases of diarrhea among Danish children for which no etiological agent is detected. This study investigated the associations between gastroenteritis-related morbidities (diarrhea, fever, and vomiting) and gut microbial community in well-nourished, breastfeeding Danish infants. Infant stool samples, morbidity questionnaires, and diet/breastfeeding questionnaires were collected at three time points during the first 8.5 months of life. The V4-V5 region of the 16S rRNA gene was amplified from stool DNA extracts, sequenced with Illumina MiSeq, and analyzed using QIIME2. PERMANOVA, linear mixed-effects modeling, and ANCOM-BC2 were used to identify associations between infant gut microbiome and gastroenteritis-related morbidities across all visits. Logistic regression and random forest models were employed to determine whether early gut microbial alpha diversity or abundance, respectively, could predict morbidity later in infancy. Alpha diversity was negatively associated with diarrhea. IMPORTANCE: Gastroenteritis continues to cause much morbidity among infants in high-income countries, and the relationship with the gut microbiome is not fully understood, especially for well-nourished and breastfeeding infants. In the study presented here, infant stool Staphylococcales abundance (comprised of
