Competency of novice anesthesia residents in performing trans thoracic echocardiography following a structured problem-based hands-on course using a trans thoracic echocardiography simulator versus video-based training: a randomized controlled assessor-blinded trial.

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
backgroundTrans-thoracic echocardiography (TTE) improves the diagnostic skills of anesthesia trainees during the perioperative period. We compared performance between two educational intervention, simulation-based hands-on training and video-based training as measured by a novel TTE Competency Score (TCS).
methodsFifty novice anesthesia residents were randomized into an intervention group-I (received simulation-based training) and a control group-C (received video-based training). Both groups underwent evaluations of their knowledge and skills on live volunteers or ICU patients using TCS right after the training and again six months thereafter. An independent sample t-test was employed to compare TCS between the groups, while a paired t-test was used to assess intragroup TCS at the baseline, after training, and six months post-training.
resultsThe two groups had no significant difference in the pre-test assessment scores. Immediately following the training session, Group I exhibited a significantly higher TCS compared to Group C (25.2 ± 2.7 and 22.4 ± 2.5, p = 0.01). Compared to the I-group, the C-group made more attempts to achieve competence. Group I exhibited higher confidence levels both immediately and six months later. After a six-month follow-up, the TCS scores in both groups were lower than the scores recorded immediately.
conclusionThis study demonstrates that a structured, problem-based simulator course improved immediate TCS and 6-month confidence compared with video-based training. However, a decline in TCS in both groups over time highlights the need for periodic refreshers within six months to improve retention.
