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: Lead toxicity, a global health concern, damages many organs. Spirulina is a blue-green algae which has vitamins, minerals, and antioxidant properties, may alleviate injury resulting from lead toxicity. This investigation aimed to determine the protective benefits of Spirulina on acute lead toxicity. Materials and Methods: Thirty-two Wistar rats were divided into four groups of 8: Control, lead toxicity group which received lead acetate (50 mg/kg/day, i.p), EDTA group which received lead acetate + EDTA (Ethylenediaminetetraacetic acid, 50 mg/kg/day, i.p) and Spirulina group received lead acetate + Spirulina (1000 mg/kg/day, oral gavage). After one week, blood samples were taken for serum liver enzymes, testosterone, BUN (Blood Urea Nitrogen), and creatinine determination. Additionally, the livers, kidneys, and testes were dissected, weighed, and saved for evaluation of oxidant-antioxidant factors and histopathological studies. Antioxidant status was assessed by measuring the levels of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and catalase in liver, kidney and testis homogenates. Results: Our results showed that lead toxicity caused a reduction in the organ index, which was improved by EDTA and Spirulina treatment. Lead toxicity significantly increased serum glutamic oxaloacetic transaminase (SGOT), serum glutamic-pyruvic transaminase (SGPT), alkaline phosphatase (AlkP), and creatinine, which were significantly reduced by Spirulina treatment. Histological studies indicated that treatment by EDTA and Spirulina improved histological changes in liver, kidney and testis organs. In addition, treatment with spirulina reduced MDA and increased SOD and catalase in liver and testis tissues. Conclusion: Spirulina improved complications of lead toxicity by improving redox balance. These promising results suggest its potential as a protective agent, though further studies are warranted to elucidate the precise mechanisms and clinical applicability.
