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
BackgroundCystitis glandularis is a metaplastic lesion of the bladder mucosa. The underlying pathogenesis of cystitis glandularis and the potential association between the therapeutic effects of pachymic acid and ferroptosis remain unclear.MethodsHuman bladder epithelial cells (SV40-immortalized human urothelial cells-1 (SV-HUC-1)) and Sprague-Dawley rat bladders were treated with lipopolysaccharide, with pachymic acid and ferrostatin-1 used as interventions. Cell viability was determined using the Cell Counting Kit-8 (CCK-8) assay. Levels of reactive oxygen species, glutathione, and malondialdehyde were quantified in both cells and tissues. Levels of tumor necrosis factor-α, interleukin-1β, and interleukin-6 in rat bladder tissues were quantified using enzyme-linked immunosorbent assay kits. The expression levels of nuclear factor erythroid 2-related factor 2, glutathione peroxidase 4, and solute carrier family 7 member 11 were analyzed, and bladder inflammation was evaluated using hematoxylin and eosin staining. The mitochondrial ultrastructure of bladder tissue was examined using transmission electron microscopy.ResultsLipopolysaccharide treatment reduced cell viability, increased malondialdehyde and reactive oxygen species levels, and decreased glutathione levels in both cells and tissues. The levels of nuclear factor erythroid 2 related factor 2, glutathione peroxidase 4, and solute carrier family 7 member 11 were reduced, while those of inflammation markers were elevated. Lipopolysaccharide stimulation induced mitochondrial structural damage in rat bladder tissues. Treatment with pachymic acid and ferrostatin-1 partially reversed these effects.ConclusionsFerroptosis plays a critical role in lipopolysaccharide-induced cystitis glandularis. Pachymic acid may alleviate cystitis glandularis by inhibiting ferroptosis, offering a novel therapeutic strategy for the clinical management of this disease.
