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
purposeIn cisplatin-induced premature ovarian failure (POF) mice, granulosa cells showed a high level of ferroptosis. Previous research has indicated that the fat mass and obesity-associated protein/activating transcription factor 4 (FTO/ATF4) axis was involved in the regulation of ferroptosis. The purpose of this study was to explore the role of the FTO/ATF4 axis in cisplatin-induced ferroptosis in granulosa cell.
methodsThe extent of ferroptosis was assessed by transmission electron microscopy (TEM) and ROS, GPX, GSH, and MDA assays. Western blotting was used to evaluate the protein expression levels of ferroptosis-related molecules. Ferroptosis activator and inhibitor were also used.
resultsWe found that ferroptosis increased in a concentration-dependent manner in cisplatin-induced injured granulosa cells, accompanied by the downregulation of FTO. In addition, gain- and loss-of-function studies showed that FTO affects ferroptosis in injured cells by regulating ATF4 expression. Ferrostatin-1 inhibited the effect of FTO downregulation on injured granulosa cells ferroptosis, and erastin reversed the protective effect of FTO on ferroptosis in injured granulosa cells. Finally, melatonin was used, and we found that melatonin reduced ferroptosis in cisplatin-induced injured granulosa cells by upregulating FTO expression.
conclusionOur study demonstrated that cisplatin induced granulosa cell ferroptosis by downregulating the expression of FTO. ATF4 was identified as a downstream target of FTO, and overexpression of ATF4 reversed the effects of decreased FTO on ferroptosis. Additionally, melatonin mitigates the cytotoxic effects of cisplatin by upregulating FTO expression. The melatonin-FTO-ATF4 signaling pathway plays a vital role in the treatment of cisplatin-induced POF.
