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
BACKGROUND Neonatal gut diversity is influenced by birth conditions and probiotic/antibiotic use. The gut microbiota affects brain development, immunity, and risk of diseases. Preterm infants, especially in neonatal intensive care units (NICUs), have different gut flora from full-term infants, suggesting in utero microbial colonization. This study examined gut microbiota changes in 92 NICU preterm infants in China. MATERIAL AND METHODS We collected data on 92 preterm infants admitted to the NICU immediately after birth, and fecal samples were collected on days 1, 3, 7, 14, 21, 28, and 60. We analyzed changes in intestinal bacteria through 16S rRNA sequencing, predicted the change in gut microbiota function over time, and compared the effects of main feeding modality on the intestinal bacteria of preterm infants. RESULTS At the phylum level, the top 5 phyla in total accounted for 99.69% of the abundance, in decreasing order of abundance: Proteobacteria, Firmicutes, Actinobacteria, Tenericutes, and Bacteroidetes. At the genus level, the top 10 genera in terms of abundance accounted for a total of 90.90%, in decreasing order of abundance: Pseudomonas, Staphylococcus, Klebsiella, Escherichia-Shigella, unclassified Enterobacteriaceae, Staphylococcus, Clostridium-sensu-stricto-1, Streptococcus, Sphingomonas, and Ureaplasma. The abundance of Proteobacteria and Pseudomonas showed a decreasing trend at first, reached a minimum at day 14, and then an increasing trend, while the opposite trend was observed for Firmicutes. The metabolic function of the bacterial community changed greatly at different time points. The abundance of Proteobacteria at the phylum level and Streptococcus at the genus level in formula-fed infants were significantly higher than in breast-fed infants. CONCLUSIONS Between 1 and 60 days, the gut microbiome in preterm infants in the NICU changed with changes in feeding patterns, with the main gut bacteria being from the phyla, Proteobacteria, and Pseudomonas.
