Inhibitory effects of thymol and carvacrol on heme degradation and oxidative products due to tartrazine:

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
The pathology of many diseases arises from oxidative stress and cell destruction. Antioxidant application is one of the most important ways for oxidative stress prevention in the cells and its consequent effects. The present study investigated the natural antioxidants inhibitory effects of thymol and carvacrol on human hemoglobin treated with tartrazine. Purified hemoglobin from human blood samples was treated with tartrazine alone or in combination with mentioned natural antioxidants (thymol and carvacrol). Treated samples were picked up at regular time intervals and changes were followed by UV-visible and fluorescence spectroscopic assays, and circular dichroism spectroscopy (CD). The result of fluorescence spectroscopy revealed that thymol and carvacrol prevented the production of heme-degradation products and advanced glycation end products (AGEs) caused by hemoglobin oxidation with tartrazine. The results of UV-visible and fluorescence spectroscopy revealed the positive effect of these antioxidants on preserving Hb folding, heme, and especially the porphyrin ring surrounding the microenvironment. The results of the circular dichroism (CD) assay showed the protection of alpha helix structure in hemoglobin treated with thymol and carvacrol compared to the control sample. The mentioned antioxidants caused hemoglobin resistance against tartrazine's destructive effect by preventing both heme degradation and glycemic toxins formation and thus reducing the rate of oxidative processes. This matter can be important for various pharmaceutical, health, and cosmetic industries.
