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
Undergraduate experimental courses are a key way to cultivate students' scientific research practice and innovation abilities. The traditional experimental teaching mode of "emphasizing process and neglecting inquiry" limits the development of students' scientific research thinking and innovation ability. Especially in the field of analytical chemistry， technical teaching involving techniques such as GC-MS is limited to confirmatory experiments， which is difficult to meet practical needs. In this paper， a comprehensive experimental teaching scheme integrating method development and problem exploration is constructed based on the development of detection methods for pyrimidine fungicides in soil. It covers four links： method establishment， technology optimization， data analysis and extended verification. The teaching method of group cooperation and personal display is adopted to guide students to optimize the relevant parameters of QuEChERS-GC-MS method and encourage them to independently discover and solve problems independently. The results showed that 1% acetic acid acetonitrile （20 mL） was the optimal extraction solvent； 500 mg PSA+500 mg C18+500 mg GCB+1.2 g MgSO
