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
aimsThis study aimed to evaluate the hepatotoxicity of buprenorphine in lactating rat pups of buprenorphine-injected mothers. Buprenorphine (BUP), a semisynthetic opioid, is increasingly administrated as a first-line standard maintenance treatment for opioid dependence due to its high safety and efficacy compared to other opioids. Numerous studies have confirmed the safety of BUP maintenance treatment in addicted patients.
objectivesThis study was designed to assess the effects of BUP on the activities of liver enzymes, oxidative parameters, and liver histopathological changes in pups born to a mother exposed to this drug during lactation.
methodsBUP at a dose of 0.5 or 0.1 mg/kg was subcutaneously administrated to lactating rats for 28 days. At the end of the experiment, the pups were anesthetized, and blood samples were obtained from their hearts for measuring liver enzymes. Then the livers of the animals were dissected to measure oxidative stress parameters. In addition, the liver samples were fixed for histopathological evaluation.
resultsThe findings indicated a decrease in the activities of serum liver enzymes (ALT and AST) of the pups born to mothers exposed to 0.5 and 1 mg/kg of BUP during lactation. BUP could not change malondialdehyde (MDA), glutathione (GSH), nitric oxide (NO) levels, nor superoxide dismutase (SOD) activity in the liver tissue of animals. Some vacuolated hepatocytes with dark, eccentric nuclei, necrosis with karyolytic nuclei, mitotic figures, and multiple binucleated cells were seen in the pups which received 1 mg/kg of BUP.
conclusionIn conclusion, BUP may induce liver dysfunction in pups born to mothers exposed to this drug during lactation.
