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
Mass spectrometer is an important component of the instrumental analysis courses in higher education. However， conventional commercial mass spectrometers usually lead to an imbalance between theory and practice in teaching， because of their characteristics of large size， high price and complicated operations， which makes it difficult to establish a direct link between instrument structure and detection principles. The miniature mass spectrometer shares the same core principles as commercial mass spectrometers. Equipped with an atmospheric pressure ionization （API） source， it significantly reduces sample preparation requirements， and enables rapid analysis of complex samples. The unique capability of the linear ion trap mass analyzer to scan， store， and eject ions enables a dramatic reduction in instrument size. The miniature ion funnel transmission technology and atmospheric pressure continuous sampling interface ensure high repeatability and rapid analysis， allowing compatibility with various atmospheric pressure ion sources for diverse sample types. In terms of performance， the miniature mass spectrometer has a mass-to-charge （
