Neurotoxic, Hepatotoxic and Nephrotoxic Effects of Tramadol Administration in Rats.
Article in Journal of molecular neuroscience : MN, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
The current study was performed to study the tramadol HCL toxic effects on the brain, liver, and kidney of adult male rats. Forty male adult albino rats were divided into 4 groups; the first one was considered as a control group, the others were orally administrated with 25, 50, and 100 b.wt. representing therapeutic, double therapeutic, and 4 times therapeutic doses, respectively, of tramadol HCL daily for 1 month. Serum and brain, hepatic, and renal tissues were collected for biochemical and molecular investigations. Tramadol HCL resulted in a significant increase in the brain serotonin, 8-hydroxy-2'-deoxyguanosine (8-OHdG), and malonyldialdehyde (MDA) levels with a significant decrease in the reduced glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) activities. At the same line, hepatic and renal 8-OHdG and MDA levels showed a significant increase with a significant decrease in reduced glutathione (GSH), CAT, and SOD activities. In addition, hepatic and renal function parameters including serum alanine amino transferase (ALT), aspartate amino transferase (AST), urea, and creatinine were increased in a dose-dependent manner. At the molecular levels, hepatic cytochrome P5402E1 (CYP2E1), renal Kidney Injury Molecule-1 (KIM-1), and tissue inhibitor of metalloproteinase-1 (TIMP-1) showed also a significant increase in the expression levels. Histopathological evaluation of the brain confirmed the above biochemical results. In conclusion, tramadol HCL induced neurotoxic, hepatotoxic, and nephrotoxic effects in a manner relative to its concentration by affecting brain serotonin levels and hepatic and renal function, with the production of DNA damage and oxidative stress.
