Transesophageal Echocardiography - Student Early Engagement in Didactic Sonography (TEE-SEEDS).
Article in BMC medical education, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTransesophageal echocardiography (TEE) is an essential diagnostic tool for many cardiac pathologies. This study's hypothesis is that a simulator-based TEE training method would improve the confidence, knowledge, and skills of medical students without prior TEE instruction, and that more experienced ultrasound students would benefit the most.
methodsIn phase one, second-year and fourth-year medical students watched a TEE video before training and took pre- and post-training confidence surveys and knowledge quizzes. The training session was a live TEE simulator demonstration, after which participants' ability to obtain four TEE views and identify major anatomical structures was tested. In phase two, a larger cohort of second-semester first-year medical students underwent the same training curriculum.
resultsThe second- and fourth-year students' knowledge scores significantly improved by 37.9% and 34.0%, respectively. The first-, second-, and fourth-year students significantly increased their confidence across all categories, including: cardiac anatomy (20.0%, 16.9%, 37.7%), general ultrasound (34.6%, 29.8%, 40.8%), cardiac ultrasound (51.1%, 47.6%, 65.0%), and TEE (252.9%, 400%, 446%). The greatest increase was seen in the fourth-year student cohort for TEE confidence, with a pre-intervention mean score of 1.3 (SD 0.49) and a post-intervention mean score of 7.1 (SD 1.21). All participants successfully demonstrated TEE skills.
conclusionsThe data suggest that the tested TEE training protocol increases medical students' TEE knowledge, confidence, and skills, demonstrating the benefits of implementing TEE training into medical curricula.
