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
Introduction: Arterial puncture is a fundamental procedural skill that medical trainees must acquire. However, it carries a risk of serious complications, particularly when performed by inexperienced operators. This study aimed to develop an arterial puncture part-task trainer to enhance skill acquisition among medical students and to compare arterial puncture performance between simulator-based training and conventional training in fifth-year medical students. Methods: This experimental study was conducted from January 26, 2024, to April 11, 2024, and included twenty-two fifth-year medical students undergoing emergency department training at Ramathibodi Hospital. Participants performed arterial punctures on patients, and all procedures were recorded on video. Three independent raters evaluated the recordings using a standardized procedural checklist. The primary outcome was the total arterial puncture procedural checklist score during the initial patient-based assessment. The intervention group additionally underwent a reassessment two weeks after simulator training to evaluate skill retention. Continuous variables were analyzed using Student's Results: During the study period, the intervention group (n=10) achieved a significantly higher total skill score (37.1 ± 3.2) compared to the control group (n=12), which had a score of 33.25 ± 3.8 (p = 0.016). Additionally, the total self-confidence scores significantly increased from 23.5 to 25.6 (p = 0.040). Participants expressed strong satisfaction with the arterial puncture part-task trainer, with a mean rating of 3.68 for its suitability for practicing arterial puncture and a mean rating of 3.86 for its potential use in medical student training. Conclusion: Although this pilot study involved a relatively small sample size, the arterial puncture part-task trainer simulator significantly improved both procedural skill performance and self-confidence in performing arterial punctures.
