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
Sheng Mai San (SMS), a traditional Chinese medicine formula for treating qi and yin deficiency, is widely used in the management of conditions such as cardiovascular diseases and heatstroke. However, its role in mitigating heat stress (HS)-induced liver injury remains underexplored. In this study, a rat model of HS was established under high-temperature and high-humidity conditions, and SMS was administered as an intervention. The pharmacodynamic effects of SMS were comprehensively evaluated through histopathological examination, detection of heat shock protein 70 (HSP70) and heat shock protein 90(HSP90) expression, and analysis of liver function biomarkers (AST, ALT). Meanwhile, oxidative stress indicators were measured using biochemical assay kits (GSH, SOD, CAT, MDA, T-AOC), and transmission electron microscopy was employed to observe mitochondrial ultrastructure, thereby assessing the protective effects of SMS on hepatic oxidative stress and mitochondrial damage induced by HS. In vitro, BRL-3A cells were cultured, subjected to HS, and treated with SMS. Cell viability was assessed using the CCK-8 assay, and changes in mitochondrial reactive oxygen species (ROS) levels, mitochondrial permeability transition pore (MPTP) opening, and mitochondrial membrane potential (MMP) were evaluated using fluorescent probes. The results showed that SMS effectively restored HS-induced histopathological damage in rat liver tissues, reduced serum AST and ALT levels, and downregulated the mRNA expression of HSP70 and HSP90 in liver tissues. Meanwhile, SMS strengthened the hepatic antioxidant system by increasing the levels of GSH, SOD, T-AOC, and CAT, while decreasing MDA content. In vitro experiments confirmed that SMS increased the viability of BRL-3A cells, reduced ROS production, improved MPTP opening/closing regulation, and stabilized MMP. This study provides a clinical reference for its application in treating HS-related conditions in humans and animals.
