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
The aim of this study was to explore the molecular mechanisms underlying carbamazepine (CBZ)-induced testicular toxicity and testosterone reduction in rats. For this purpose, Sprague-Dawley (SD) rats were intervened with 200 mg/kg CBZ for 12 weeks, and R2C cells were exposed to CBZ at concentrations of 0.5, 1 and 1.5 mM for 24 h. HE, Tunel, ELISA, immunofluorescence staining, RT-qPCR, and western blot were used to reveal the effects of CBZ on spermatozoa quality, testicular tissue structure, testosterone level and testosterone synthesis-related enzymes in rats. The results showed that CBZ significantly damaged the testicular tissue structure of rats, induced cell apoptosis, down-regulated the gene and protein expression levels of testosterone synthesis-related enzymes (STAR, TSPO, 17β-HSD and 3β-HSD), inhibited the expression of related proteins in the cAMP/PKA/CREB signalling pathway, and suppressed testosterone levels. In addition, the use of Db-cAMP (a PKA activator) significantly upregulated the protein expressions of PKA and p-CREB, evidently alleviated the CBZ-induced decrease in testosterone levels. In conclusion, CBZ induced testosterone resynthesis by inhibiting the cAMP/PKA/CREB pathway, affecting the expression of steroid synthesis-related enzymes and reducing testosterone levels.
