Skill retention with ultrasound curricula.
Trial report in PloS one, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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
backgroundImplementation of a point of care ultrasound curricula is valuable, but optimal integration for internal medicine residency is unclear. The purpose of this study was to evaluate if a structured ultrasound curriculum vs. structured ultrasound curriculum plus supervised thoracic ultrasounds would improve internal medicine residents' skill and retention 6 and 12 months from baseline.
methodsWe conducted a randomized controlled study evaluating internal medical residents' skill retention of thoracic ultrasound using a structured curriculum (control, n = 14) vs. structured curriculum plus 20 supervised bedside thoracic ultrasounds (intervention, n = 14). We used a stratified randomization based on program year. All subjects attended a half-day course that included 5 lectures and hands-on sessions at baseline. Assessments included written and practical exams at baseline, immediately post-course and at 6 and 12 months. Scores are reported as a percentage for the number of correct responses/number of questions (range 0-100%). The Mann Whitney U and the Friedman tests were used for analyses.
resultsTwenty-eight residents were enrolled. Two subjects withdrew prior to the 6-month exams. Written exam scores for all subjects improved, baseline median (IQR) 60 (46.47 to 66.67) post-course 80 (65 to 86.67), 6-month 80 (66.67 to 86.67) and 12-month 86.67 (80 to 88.34), p = <0.001. All subjects practical exam scores median (IQR) significantly improved, baseline 18.18 (7.95 to 32.95), post-course 59.09 (45.45 to 70.45), 6 month 71.74 (60.87 to 82.61) and 12-month 76.09 (65.22 to 88.05), p = <0.001. Comparing the control group to the intervention group, there were statistically significant higher scores, median (IQR), in the intervention group on the practical exam at 6 months 63.05 (48.92 to 69.57) vs. 82.61(72.83 to89.13), p = <0.001.
conclusionIn this cohort, internal medicine residents participating in a structured thoracic ultrasound course plus 20-supervised ultrasounds achieved higher practical exam scores long-term compared to controls.
