1 · What the graph read from it

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.

2 · The registry

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

There are few studies on the genomics of heat stress response and the molecular mechanisms of thermoregulation. In this experimental model, Sprague-Dawley rats were subjected to temperatures of 22 ± 1 °C (control group; CT) and 42 °C for varying durations (30, 60, and 120 min, H30, H60, and H120, respectively). Significantly high rectal body temperatures were recorded post-heat stress across all treatment groups. Adrenal corticosterone levels increased significantly, especially in H120 group. Heat stress predictive accuracies of adrenal corticosterone at H60 and H120 were higher with relatively high sensitivity and AUC greater than 0.85. RNA-sequencing of adrenal gland tissue from CT vs. H30, CT vs. H60, and CT vs. H120 identified 4, 8 and 8 known; and 72, 305 and 160 de novo differentially expressed lncRNA (DElncRNAs), respectively. A total of 61, 208, and 124 genes were found to interact with DElncRNAs in the three comparisons, of which 1, 24, and 20 were differentially expressed transcripts (DETs), respectively. Among these known DElncRNAs, Gng 2-202, MAFK-203, Rab32-201, AABR07048992.1-201 were enriched in all three comparisons. Functional enrichment and interaction network analysis of DETs interacting with DElncRNAs indicated their enrichment in pathways related to inflammation-metabolism nexus determined by DETs like Jun, Map3k5, Cyp1b1, Tiparp, Ezh2, and Cbx4. This study will supplement our understanding of the transcriptome level response mechanism of rat adrenal tissue under heat stress and provide theoretical reference for the study of mammalian body response to heat stress stimulation.
