Effects of heat degradation of betanin in red beetroot (Beta vulgaris L.) on biological activity and antioxidant capacity.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Betanin is a red pigment of red beetroot (Beta vulgaris L.), providing the beneficial effects to maintain human health. Betanin is involved in the characteristic red color of red beetroot, and used as an edible dye. Betanin is known to be a highly unstable pigment, and water solutions of betanin are nearly fully degraded after heating at 99°C for 60 min in the experimental conditions of this study. The present study investigated the effects of red beetroot juice (RBJ) and betanin on immune cells, and found that stimulation with RBJ and betanin induces interleukin (IL)-1β, IL-8, and IL-10 mRNA in a human monocyte derived cell line, THP-1 cells. This mRNA induction after stimulation with RBJ and betanin was not significantly changed after heat treatment when attempting to induce degradation of the betanin. Following these results, the effects of heat degradation of betanin on the inhibition of lipopolysaccharide (LPS) induced nitric oxide (NO) production in RAW264 cells and the antioxidant capacity were investigated. The results showed that the inhibition activity of RBJ and betanin with the LPS induced NO production is not altered after heat degradation of betanin. In addition, the results of FRAP (ferric reducing antioxidant power) and DPPH (1,1-Diphenyl-2-picrylhydrazyl) assays indicate that a not inconsiderable degree of the antioxidant capacity of RBJ and betanin remained after heat degradation of betanin. These results suggest that it is important to consider the effects of degradation products of betanin in the evaluation of the beneficial effects of red beetroot on health.
