SpacED POCUS: A Randomized Controlled Trial of an Adaptive Spaced Education POCUS Curriculum for Medical Students.
Article in POCUS journal, 2025. 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
This study evaluated the effectiveness, retention, engagement, and acceptability of adaptive spaced education (spacED) for improving the accuracy of point of care ultrasound (POCUS) image interpretation by medical students. From July 2022-May 2023, students (n=36) were randomized into two groups and each assigned 50 unique POCUS cases: cardiac/vascular or lung/FAST. Each one served as the control for the other group. We measured effectiveness (% posttest 1 - % pretest), six-month retention (% posttest 2 - % posttest 1), engagement (% cases completed), and acceptability (% would recommend). Twenty-nine students (81%) completed the study. On average, 38.6% of cases were completed over the six-month study period. There was a significant increase in test scores covering FAST (Focused Assessment with Sonography in Trauma) (+18%), lung (+25%), and vascular (+23%, all p<0.01). Six-month FAST and lung scores did not have significant loss (+3% and -10%, p >0.05). Acceptability was high; 96% of students indicated they would participate again. Despite an imperfect case completion rate, for some applications, spacED was an effective, long-lasting, and acceptable method for teaching POCUS interpretation to medical students.
