NO/NOS system dysregulation as a key molecular mechanism in chemotherapy-induced cardiotoxicity: a review.
Review in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cardiotoxicity, as a side effect of chemotherapeutic treatments, represents a major limiting factor during anti-tumour therapies. This is usually evident by decreased cardiac function, and the cardiovascular diseases linked to chemotherapeutic agents can range from mild arrhythmias and hypertension to myocardial injuries and heart failure. One of the most important regulators of cardiovascular function is nitric oxide (NO), a small signalling molecule associated with multiple cardioprotective properties. The activity of NO producing enzymes, the nitric oxide synthases (NOSs), is tightly regulated by pathways responsible for maintaining the cardiovascular NO homeostasis. Thus, the dysregulation of the NO/NOS system could lead to severe pathologic changes in cardiomyocytes and endothelial cells. This narrative review examines the evidence on how chemotherapeutic agents affect cardiac NOS activity and NO signalling, and explores whether NO/NOS dysregulation may be considered as a relevant mechanism in the development of chemotherapy-induced cardiotoxicity.
