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
To address the evolving demands for innovation and practical competencies in pharmaceutical education， and in alignment with the "student-centered， outcome-driven" pedagogical approach， our teaching team has undertaken a comprehensive reform of the Pharmaceutical Analysis curriculum. We designed and implemented an integrative， research-based laboratory experiment for undergraduate students. Centered on the design and application of functional materials， the experiment guides students through the independent synthesis of a halogen-bonded organic framework， designated as XOF-1， followed by systematic structural characterization， performance evaluation， and analytical application. The experiment is grounded in real-world environmental analysis challenges， requiring students to employ the synthesized material as a dispersive solid-phase extraction （DSPE） adsorbent for the selective enrichment of typical brominated flame retardants， including tetrabromobisphenol A （TBBPA）， tetrachlorobisphenol A （TCBPA）， and hexabromobenzene （HBB）， and to achieve the removal of TBBPA from actual water samples. The instructional process fully encompasses the workflow from material preparation and structural characterization to method development and performance assessment， enabling students to experience a complete research pathway from material design to practical application. This approach immerses them in the scientific inquiry cycle of theory-design-experiment-analysis. Through this experiment， students gain solid proficiency in synthesizing and characterizing functional materials and applying them to sample pretreatment. By engaging in experimental design， condition optimization， and data interpretation， they develop critical thinking， problem-solving skills， and capacity for independent inquiry. The exercise fosters deep integration of theoretical knowledge and practical skills， stimulates research interest， strengthens innovative and applied mindsets， and cultivates a sense of professional responsibility in environmental and public health. Ultimately， it achieves a cohesive blend of knowledge acquisition， competency development， and value cultivation， fulfilling the overarching goal of holistic education through experimental learning.
