Nicotinamide Riboside Attenuates Cisplatin-Induced Hepatorenal Toxicity Through Restoration of NAD

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
backgroundCisplatin is a widely used chemotherapeutic agent whose clinical application is often limited by severe hepatorenal toxicity associated with oxidative stress and cellular injury. Nicotinamide riboside (NR), a natural precursor of nicotinamide adenine dinucleotide (NAD+), has emerged as a promising cytoprotective compound with antioxidant and metabolic regulatory properties. This study investigated the protective effects of NR against cisplatin-induced hepatorenal toxicity and explored its potential mechanisms of action.
methodsThirty-six adult male Wistar rats were randomly assigned to four groups (
resultsCisplatin administration induced marked hepatorenal injury, evidenced by significant elevations in serum KIM-1 (395.27 vs. 116.04 ng/mL), urea (71.16 vs. 21.33 mg/dL), creatinine (3.49 vs. 0.26 mg/dL), AST (325.83 vs. 95.16 U/L), and ALT (102.83 vs. 45.50 U/L), accompanied by dyslipidemia, oxidative stress, and severe histopathological alterations. NR treatment significantly attenuated these changes, reducing KIM-1, urea, creatinine, AST, and ALT by 55.5%, 47.8%, 48.1%, 55.4%, and 33.5%, respectively, compared with the cisplatin group. NR also improved antioxidant status by increasing GSH and SOD levels while reducing MDA and NO concentrations. Hepatic NAD
conclusionsNicotinamide riboside exerts protective effects against cisplatin-induced hepatorenal toxicity that are mechanistically linked to activation of the Nrf2/NQO1 antioxidant pathway and restoration of hepatic NAD
