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
Despite the diverse applications of γ radiation in radiotherapy, industrial processes, and sterilization, it causes hazardous effects on living organisms, such as cellular senescence, persistent cell cycle arrest, and mitochondrial dysfunction. This study evaluated the efficacy of curcumin nanoparticles (CNPs) in mitigating mitochondrial dysfunction and cellular senescence induced by γ radiation in rat brain tissues. Four groups of male Wistar albino rats (n = 8 per group) were included: (Gr1) the control group; (Gr2) the CNPs group (healthy rats receiving oral administration of curcumin nanoparticles at a dose of 10 mg/kg/day, three times per week for eight weeks); (Gr3) the irradiated group (rats exposed to a single dose of 10 Gy head γ irradiation); and (Gr4) the irradiated + CNPs group (irradiated rats treated with CNPs). The data obtained demonstrated that oral administration of CNPs for eight weeks attenuated oxidative stress in γ-irradiated rats by lowering the brain's lipid peroxidation level [malondialdehyde (MDA)] and enhancing antioxidant markers [superoxide dismutase (SOD), reduced glutathione (GSH), and total antioxidant capacity (TAC)] (P < 0.05). In addition, CNPs significantly increased mitochondrial function by improving complex I, complex II, and ATP production levels compared to the irradiated group. In irradiated rats, CNPs also showed anti-neuroinflammatory effects by reducing brain interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-ĸB) levels (P < 0.05). Moreover, CNPs administered to irradiated rats significantly reduced brain β-galactosidase activity and the expression levels of p53, p21, and p16 genes (P < 0.05) while concurrently inducing a significant increase in AMPK mRNA expression compared to the irradiated group. In conclusion, CNPs ameliorated the neurotoxicity of γ radiation and hold promise as a novel agent to delay cellular senescence via their combined antioxidant, anti-inflammatory, and mitochondrial-enhancing properties.
