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 cochlea is susceptible to damage from ototoxic agents such as cisplatin, yet the mechanisms underlying cochlear injury remain incompletely understood. Mast cells (MCs), key immune players in allergic and inflammatory responses, have recently been identified in the rodent cochlea and implicated in cisplatin-induced ototoxicity. Our study investigated the role of MC degranulation in cochlear damage and evaluated the activation capacity of cochlear-resident MCs. Bone marrow-derived MCs (BMMCs) were cultured and induced to degranulate via IgE-anti-DNP/DNP stimulation, and the supernatants were applied to cochlear explants. Cochlear explants were also treated with Compound 48/80 (CP48/80) or cisplatin to assess MC activation. Morphological changes were assessed and hair cells (HC) quantified via phalloidin staining, while ELISA measured mediator release. Supernatants from degranulated BMMC induced a dose-dependent HC loss and tissue damage. A significant chymase and tryptase release was triggered by CP48/80 from cochlear MCs, with chymase elevation detected even at low concentrations. Cochlear MCs were rapidly activated by cisplatin exposure, elevating chymase and histamine levels, and the effects were attenuated by the MC stabilizer sodium cromolyn. Notably, tryptase remained undetectable post-cisplatin treatment, suggesting tissue-specific MC responses. These findings establish MC degranulation as an early event in cisplatin-induced cochlear injury, mediated by chymase and histamine. Our study highlights MCs as potential therapeutic targets for mitigating ototoxicity and underscores the need to explore MC-driven pathways in hearing loss.
