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
backgroundClinical decision-making is a core nursing competency that develops progressively through education and practice. However, nursing students frequently report reduced self-confidence and increased anxiety when required to make clinical decisions. High-fidelity simulation (HFS) provides a safe, realistic environment to practice clinical decision-making and may influence these psychological determinants. Longitudinal studies on how repeated exposure to HFS affects anxiety and self-confidence across an entire nursing curriculum remain limited.
methodsA four-year longitudinal study examined changes in nursing students' self-confidence and anxiety in clinical decision-making during repeated annual exposure to HFS within a single cohort. A total of 143 students completed pre- and post-intervention questionnaires using the Nursing Anxiety and Self-Confidence with Clinical Decision-Making-High-Fidelity Simulation scale (NASC-CDM-HFS). Linear mixed-effects models with random intercepts for participants examined year-by-year changes in self-confidence and anxiety, adjusted for age and prior healthcare experience. The anxiety models were further adjusted for baseline self-confidence levels.
resultsPre-intervention self-confidence increased naturally across the program, whereas pre-intervention anxiety declined, indicating growing familiarity with clinical practice. After participating in HFS, significant improvements were observed during the first year. Self-confidence increased (b = 6.64, 95% CI [4.17, 9.11]) and anxiety decreased (b = -2.90, 95% CI [-5.27, -0.68]). In subsequent years (Y2-Y4), HFS produced no additional statistically significant effects.
conclusionHigh-fidelity simulation enhancess self-confidence and reduces anxiety during clinical decision-making among novice nursing students. However, significant effects were only found during the first training year. This suggests that the psychological impact of HFS is strongest when students are exposed to simulationtraining for a first time. To repeat these psychological benefits throughout the curriculum, simulation activities should be progressively adapted in complexity, integrated more frequently, and aligned with students' advancing clinical competencies.
