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
Animal experimentation is conducted under regulatory and institutional frameworks that require ethical standards, safety management, scientific validity, and compliance with relevant guidelines. Accordingly, institutions that conduct preclinical research are responsible for providing structured training programs that prepare researchers to conduct animal experiments appropriately. However, empirical evaluations of such training programs and their outcomes remain limited. This study evaluated a comprehensive preclinical animal experimentation training program covering ethics, regulatory requirements, safety, and technical knowledge, using survey data collected from researchers who completed the program at Samsung Medical Center. The Kirkpatrick training evaluation model was applied as an analytical framework, and partial least squares structural equation modeling (PLS-SEM) was used to explore researchers' perceptions of animal experimentation conduct. The results demonstrated that the training program was associated with improved researcher perceptions, supported by acceptable reliability and validity of the measurement instrument. In particular, perceptions related to animal research ethics were significantly associated with experimental performance. An exploratory structural model was developed to identify key determinants of researcher perceptions and to support future refinement of training evaluation approaches. These findings suggest that well-designed training programs can foster ethically grounded and practically oriented attitudes among researchers, thereby strengthening accountability in animal experimentation and supporting the implementation of the Replacement, Reduction, and Refinement (3Rs) principles. This study provides evidence-based insights for institutions, training coordinators, and oversight bodies seeking to improve laboratory animal research training programs.
