A prospective case-control study on online teaching of ultrasonography skills to medical students during COVID-19 pandemic.
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
introductionA new Online interactive Ultrasound Teaching (OUT) was developed in our institution in March 2021 during COVID-19 outbreak.
methodsThis is a case control study on 65 final year medical students to compare OUT with conventional face-to-face ultrasound tutorials. There were 31 female and 34 male students. Median age was 23 years old (Range 21-30). Students were randomly assigned into two different teaching groups. Competency in conducting ultrasonic exam was assessed by Objective Structured Assessment of Ultrasound Skills (OSAUS).
results32 students were randomized into the control group (face to face teaching) while 33 students were randomized into the case group (OUT). Baseline demographic characteristics were comparable between the two groups (
conclusionUltrasonographic skills performance was comparable between students who were taught by OUT and conventional face-to-face tutorial.
