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
China is the world's largest producer and consumer of aquatic products. Insecticides， as well as veterinary drugs， such as quinolones， macrolides， nitroimidazoles， sulfonamides， and amphenicols， are widely used in aquaculture. These compounds play crucial roles in preventing， controlling， and treating diseases in aquatic organisms， improving feed conversion rates， and promoting the healthy growth of farmed species. However， the illegal use of veterinary drugs， their overuse， and noncompliance with drug withdrawal periods by farmers can lead to aquatic products containing veterinary drug residues. This study focused on fish， shrimp， and crabs with the aim of meeting the green-development needs of China's aquaculture industry， strengthening risk warnings and preventing veterinary drug residues in aquatic products， enhancing the quality and competitiveness of farmed aquatic products， and promoting the sustainable development of the aquaculture industry. Instrumental working conditions were optimized， and the extraction solvent， extraction method， purification materials， and the redissolution solvent used in the sample-pretreatment process were determined. These efforts led to the establishment of a protocol for the detection of 50 veterinary drug residues， including quinolones， macrolides， nitroimidazoles， sulfonamides， amphenicols， and insecticides， in fish， shrimp， and crabs， which involved one-step pretreatment with a composite purification column in combination with ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）. A 5-g sample was extracted with a 1.0% acetic acid solution， dehydrated with anhydrous sodium sulfate， and purified using a FAVEX purification column， after which the purified solution was nitrogen-blown to near dryness. The residue was re-dissolved in 1.0 mL of 0.2% formic acid aqueous solution-methanol （9∶1， v/v） ， filtered， and then separated using a Waters ACQUITY UPLC
