1 · What the graph read from it

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.

2 · The registry

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

introductionTeaching cardiac ultrasound (CU) image acquisition requires hands-on practice under qualified instructors supervision. We assessed the efficacy of teaching medical students by their previously trained classmates (teaching assistants [TAs]) compared to teaching by expert trainers (cardiologists or diagnostic medical sonographers.

methodsSixty-six students received 8-hour CU training: 4-hour lectures on ultrasound anatomy and imaging techniques of 6 main CU views (parasternal long [PLAV] and short axis [PSAV]; apical 4-chamber [4ch], 2-chamber [2ch], and 3-chamber [3ch]; and sub costal [SC]) followed by 4 hours of hands-on exercise in groups of ≤5 students under direct supervision of a TA (group A: 44 students) or a qualified trainer (group B: 22 students). Students' proficiency was evaluated on a 6-minute test in which they were required to demonstrate 32 predetermined anatomic landmarks spread across the 6 views and ranked on a 0-100 scale according to a predetermined key.

resultsThe 6-minute test final grade displayed superiority of group A over group B (54±17 vs. 39±21, respectively [p = 0.001]). This trend was continuous across all 6 main views: PLAV (69±18 vs. 54±23, respectively), PSAV (65±33 vs. 41±32, respectively), 4ch (57±19 vs. 43±26, respectively), 2ch (37±29 vs. 33±27, respectively), 3ch (48±23 vs. 35±25, respectively), and SC (36±27 vs. 24±28, respectively).

conclusionsTeaching medical students CU imaging acquisition by qualified classmates is feasible. Moreover, students instructors were superior to senior instructors when comparing their students' capabilities in a practical test. Replacing experienced instructors with TAs could help medical schools teach ultrasound techniques with minimal dependence on highly qualified trainers.
