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
Colors have been added to food naturally and artificially for centuries to make them look more appetizing. According to the Food and Drug Organization, eight artificial colors were registered for the nutrition application, one of them, is tartrazine, which is widely used in foods and cosmetics. Food colors significantly decrease weight and increase proteins, liver enzymes, thyroid hormones, total cholesterol, and triglyceride. Onion, as an antioxidant, can reduce the harmful effects of artificial food colors on weight gain, antioxidant activity, and blood biochemical factors. The present study aimed to evaluate the effects of the onion's antioxidant properties on serum biochemical factors and antioxidants in Wistar rats after consuming tartrazine. Eighty Rats were divided into four groups, 20 mice in each. The first group received water without additives and was considered the control, the second group received tartrazine, the third group received tartrazine with onion juice, and the fourth group received only onion juice through gastric gavage. This experiment was performed for 60 days, and then the antioxidant activities of superoxide dismutase (SOD), Catalase (CAT), glutathione peroxidase (GPx), and the biochemical parameters of high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were measured. Tartrazine decreased the antioxidant activities of SOD, CAT, GPx, and the biochemical parameters of HDL and LDL. The results showed that the consumption of tartrazine causes the production of free radicals, which is the reason for the significant reduction of antioxidant activities and serum biochemical factors. Onion, as an antioxidant in this study, reduces the effects of tartrazine on antioxidant activities and serum biochemical factors.
