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
backgroundHeat stress (HS) can impair boar testicular function, leading to reproductive issues. However, chlorogenic acid (CGA) has been shown to mitigate HS-induced damage in various livestock and poultry species. Prepuberty is an important stage of testicular development in boars after birth. However, the protective effect of CGA on testicular HS injury during prepuberty boars and the underlying mechanisms are still not fully understood.
resultsIn vivo, a total of 30 healthy boars with similar body weights and ages were obtained and randomly divided into 3 groups, which were fed a basal diet supplemented with CGA 0 (the ND_TN group), 0 (the ND_HS group) or 1,000 (the CGA_HS group) mg/kg. After being fed for 28 d, all the groups, except the ND_TN group, were treated with high temperature for 7 d, after which samples were collected from the boars and analysed. The results showed that CGA significantly mitigated the HS-induced reduction in T-AOC content in testicular tissue and sperm density. Mechanistically, multiomics analysis revealed that the genes differentially expressed by CGA and HS were predominantly associated with the glutathione metabolism pathway. The combined analysis of transcriptomics and proteomics revealed that only BLVRA was affected by both HS and CGA when the mRNA and protein levels of a gene showed differential expression with the same trend. In vitro studies confirmed that CGA modulated GPX3 expression via BLVRA, affected GPx activity, and attenuated HS-induced ROS accumulation.
conclusionsIn conclusion, prepubertal HS impairs the spermatogenic capacity of boars. BLVRA may mediate the testicular protective effect of CGA, although in vivo validation of this pathway is needed. This study contributes to elucidating the mechanisms underlying the effects of HS on prepubertal boar testicular development using multiomics approaches, laying a foundation for the potential utilization of CGA in swine production.
