Study on chronic toxicity of rhubarb extract in Sprague-Dawley rats.
Article in Heliyon, 2022. 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
Objective: The purpose of this study was to evaluate the safety of rhubarb extract. Methods: SD rats were treated with rhubarb extract at 0, 101, 405 and 1620 mg/kg/day for 52 weeks. food consumption and body weights were recorded. Blood and urine samples were collected for serum biochemical evaluation and urinalysis, and organ tissues were collected for histopathological examination. Results: The rats of 1620 mg/kg group developed diarrhea symptoms with dark brown loose stool after exposure; decreased body weight and increased food consumption were observed in the 1620 mg/kg and 405 mg/kg groups; urine WBC and NIT was significantly increased in the male and female rats of 1620 mg/kg group, and the urine pH was decreased in male rats of 1620 mg/kg group; renal tubular pigmentation was observed in the 1620 mg/kg group. Conclusion: The NOAEL of rhubarb extract on chronic toxicity (52 weeks) of Sprague-Dawley rats was 101 mg/kg in female and 94 mg/kg in male, and the LOAEL was 408 mg/kg in female and 381 mg/kg in male. The target organ of toxicity was the kidney, and the target cells was tubular epithelial cells.
