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
Purpose: Xiangqin Jiere Granules (XQJRG), a Chinese patent medicine used to treat acute fever in children caused by colds, seasonal flu, and coronavirus disease 2019 has been proven to have antipyretic and anti-inflammatory effects in young febrile rats. Fever is known to affect the host-gut microbiota crosstalk. However, the pharmacological mechanism of XQJRG in this regard remains unclear. Methods: This study utilized a young febrile rat model previously reported by our team and extended the rat body temperature monitoring period following drug administration to explore the differences in efficacy between XQJRG and the commonly used pediatric antipyretic ibuprofen. Subsequently, the colonic contents of rats were analyzed using 16S rRNA gene sequencing and untargeted metabolomics. The short-chain fatty acid content was quantified using high-throughput targeted metabolomics. The expression of short-chain fatty acid receptors and pro-inflammatory genes in the colonic tissue was evaluated using quantitative real-time PCR, Western blot, and enzyme-linked immunosorbent assay. Results: XQJRG showed a longer antipyretic duration than ibuprofen. XQJRG improved dysbiosis of the intestinal microbiota in young febrile rats, bringing its flora composition closer to that of normal rats. It significantly increased the relative abundance of Conclusion: XQJRG exhibited a more stable and persistent antipyretic effect in young febrile rats compared to ibuprofen. Its mechanism was at least partially attributed to regulating intestinal flora disorders, increasing anti-inflammatory metabolites, and inhibiting the production of inflammatory factors in young febrile rats.
