Niacin Alleviates Browning in Fresh-Cut Potatoes: Regulation of NADPH/NADH Levels Mediates ROS-Redox Homeostasis and the Ascorbate-Glutathione Cycle.

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
Niacin contents vary significantly among fresh-cut potato cultivars with different browning sensitivities, whereas its role as a browning inhibitor for fresh-cut produce has not been previously reported. In this study, potato slices were soaked in distilled water (control) or 1% food-grade niacin solution for 5 min, then stored at 4 ± 1 °C for 8 days with sampling every 2 days for physiological and molecular analyses. In particular, the optimal niacin (1%) treatment showed higher brightness and lower color change than the control. The activities of polyphenol oxidase (PPO), peroxidase (POD), and phenylalanine ammonia lyase (PAL), and phenol content were reduced. Higher activities of superoxide dismutase (SOD) and catalase (CAT), and greater glutathione accumulation, were observed following niacin treatment. Meanwhile, lower levels of malondialdehyde and reactive oxygen species (ROS), and lower nicotinamide adenine dinucleotide phosphate oxidase (NOX) activity, indicated lower oxidant damage. The contents of NADP and NAD, and activities of nicotinamide adenine dinucleotide kinase (NADK) and glucose-6-phosphate dehydrogenase (G6PDH) were improved. Furthermore, the gene expression patterns of
