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 illegal addition of substances in ordinary food poses a serious threat to food safety. Therefore， the detection and identification of such additives have long been important research areas in the field of food safety. Especially， illegal additives are showing new trends now， such as emerging functional varieties， new structural derivatives， and clandestine addition practices. Meanwhile， along with the development of online shopping and logistics， new threats pose a substantial challenge to social governance and food safety. In recent years， there are frequent cases of people consuming wild mushrooms containing hallucinogenic tryptamine toxins out of curiosity， and the abuse of tryptamine psychoactive substances also occurs from time to time. Therefore， the development of a robust and sensitive analytical method is necessary for accurately identifying the risks associated with tryptamine psychoactive substances.To address this issue， a novel method based on ultra performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） combined with an isotopic internal standard and solid-phase extraction purification technique was developed for the simultaneous determination of three tryptamines （psilocin， bufotenine and psilocybin） in ten types of ordinary foods. Several optimization procedures were undertaken， involving the chromatographic conditions， mass spectrometric parameters， and sample extraction and purification protocols. The food samples were extracted and centrifuged， followed by purification using a strong cation exchange solid-phase extraction column. The separation was carried out using a Capcell PAK ST （S-5） hydrophilic interaction chromatographic column. The multi-reaction monitoring （MRM） mode was employed for data acquisition in the positive ion mode， whereas isotopic internal standards were used to quantify the three tryptamines. It was verified that the calibration curves of psilocin， bufotenine， and psilocybin exhibited good linearities （
