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
introductionSimulation-based training (SBT) for central venous catheter (CVC) placement has been shown to improve procedural performance, reduce the number of attempts, and increase success rates. However, training for specific populations, such as pediatric patients, remains challenging. Moreover, evidence regarding the transfer of simulation-acquired skills to real clinical practice is limited. The aim of this study was to evaluate the transfer of skills acquired by anesthesiology residents following SBT in ultrasound-guided pediatric CVC placement.
methodsAfter institutional ethics committee approval, 21 anesthesiology residents were recruited to participate in an SBT program for ultrasound-guided pediatric CVC insertion. The training consisted of six individual one-hour weekly sessions with direct expert feedback, using a pediatric-specific Blue Phantom® simulation model. Pre-and post-training assessments (PRE and POST) were conducted using video-recorded procedures and evaluated by two blinded assessors using a validated Global Rating Scale (GRS). In addition, hand motion metrics were collected using the Imperial College Surgical Assessment Device (ICSAD), including total path length (TPL), number of movements (NM), and total procedure time (TPT). To assess skill transfer, the same evaluation protocol was applied during CVC insertion in pediatric patients undergoing elective cardiac surgery.
resultsFifteen residents completed the training and both PRE and POST assessments. Median GRS scores improved significantly from 34 (interquartile range [IQR], 29.5-38.0) at PRE to 47 (IQR, 44.5-47.5) at POST. Total procedure time decreased significantly from 349.4 (IQR, 264-536) to 290.2 (IQR, 232-335) seconds. No significant differences were observed in total path length or number of movements. Regarding transfer to clinical practice, 13 of 15 residents successfully completed the procedure on their first attempt in real patients. Comparison between the POST simulation assessment and the real-patient assessment showed no significant differences in median GRS scores.
conclusionsSimulation-based training significantly improved anesthesiology residents' performance in simulated ultrasound-guided pediatric CVC placement. Although not all residents were able to successfully complete the procedure in real patients, the findings suggest a potential transfer of skills acquired through simulation to clinical practice.
