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
Introduction: Synthetic anabolic hormones, which may pose a potential risk to human health, should not be used in fattening food-producing animals. Because of the hormonal effects they cause, growth-promoting compounds are banned by legislation in the EU for use in animal husbandry. Consequently, all EU member states are required to conduct monitoring tests on the content and residues of these compounds in prescribed biological matrices to ensure the safety of food consumers. The aim of this research was to develop a liquid chromatography-tandem mass spectrometry method for the detection of the residue of one such anabolic hormone, clostebol in food animal urine. Material and Methods: Clostebol and its marker metabolite residues were determined by a method involving enzymatic hydrolysis, isolation of compounds from urine on a C18 solid-phase extraction (SPE) column, purification of the extract by liquid-liquid extraction using n-pentane and a NH Results: No traces of this anabolic steroid hormone or its metabolites were found in any of the samples tested. The method was validated in accordance with the current requirements for confirmatory methods, and the determined parameters of the decision limits necessary for assessing sample compliance met the specified criteria. Conclusion: In 2023, the method was introduced for testing under the National Control Plan in Poland. Up to July 19, 2024, 53 urine samples from different animal species had been tested.
