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

purposeWe developed an interventional radiology (IR) simulator using a virtual reality system (the VR-IR simulator) to teach IR procedures to medical students. In this study, we investigated the effectiveness of this teaching method. MATERIALS AND

methodsAll ninety-nine fifth-year medical students attended a conventional classroom lecture. To teach students the actual procedure, they were randomly divided into two groups: One received conventional verbal explanations and educator demonstrations (the conventional group [n = 44]), and the other received VR-IR simulator training (the VR-IR simulator group [n = 55]). Afterward, they underwent a test using an augmented reality- (AR-) IR simulator (the VIST

resultsTwo students in the VR-IR simulator group were excluded due to VR sickness and simulator malfunction. There were no significant differences between the VR-IR simulator group and the conventional group regarding total procedure time (median [25-75% interquartile range]: 13.5 [11.8-14.5] vs. 14.3 [12.3-16.8] minutes, p = 0.11), fluoroscopic time (10.1 [8.5-13.0] vs. 11.0 [8.6-13.7] minutes, p = 0.31), and patient peak skin dose (276 [243-373] vs. 303 [239-395] mGy, p = 0.57), respectively. However, the amount of contrast media used was significantly lower (28.0 [21.0-36.2] vs. 40.0 [32.3-50.9] mL, p < 0.01) and the technical achievement scores by the radiologist (36 [34-44] vs. 31 [29-32], p < 0.01) were significantly higher in the VR-IR simulator group.

conclusionThe VR-IR simulator helped reduce the amount of contrast media in interventional procedures and improved technical achievement scores.
