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

backgroundPoint-of-care-ultrasound (POCUS) improves diagnostic accuracy and expedites lifesaving procedures. Remote areas disproportionately underuse ultrasound (US) due to a dearth of US trained professionals, imaging tools, and lack of quality assurance. Handheld US probes have been approved for diagnostic imaging but there have been limited studies examining their tele-guidance features. This study investigates whether physician tele-guidance improved ultrasound image acquisition by untrained scanners.

methodsTo determine the effectiveness of tele-guidance for ultrasound image acquisition, 30 participants (15 in each study arm: experimental and control) with no ultrasound or medical experience gathered images of the heart, right kidney, and gallbladder of a standardized patient using a handheld ultrasound probe (Butterfly iQ +). All participants watched a standardized ultrasound tutorial video and were randomized into the control or experimental group. A physician assisted the experimental group using ultrasound probe's tele-guidance feature while the control group received no assistance. Time to image acquisition was recorded for both groups, and the images were graded by 3 blinded radiologists using the RACE tool to determine image and diagnostic quality.

resultsThere was evidence that mean imaging time was greater in the control group for the heart, right kidney, and gallbladder (p < 0.0001, all; Cohen's DL: 2.0, 1.7, 3.0, respectively). Similarly, there was evidence that the predicted mean image quality for the heart, right kidney, and gallbladder was higher for the experimental group compared to the control group (3.46 versus 1.86, 4.49 versus 1.58, and 3.93 versus 1.5, respectively; p < 0.0001, all). There was also evidence that the diagnostic quality of images had a statistically higher predicted probability of meaningful interpretation for the experimental group for pericardial fluid, intraperitoneal fluid, and acute cholecystitis (p = 0.003, p < 0.0001, p < 0.0001, respectively).

conclusionsTele-guidance improves time to image acquisition and clinical applicability of ultrasound images obtained by untrained scanners.
