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
Purpose: Dorsal screw tip protrusion (DSTP) with extensor tendon injury is a well-known complication after volar plating of the distal radius. Specific fluoroscopic views such as the dorsal tangential view (DTV) and the radial groove view (RGV) have been recommended to detect DSTP. The aim of this study was to investigate the accuracy of these views before and after standardized teaching of the involved surgeons. Methods: All adult patients treated with volar plating of the distal radius between 10/2019 and 09/2020 were included. All involved surgeons were instructed on how to perform accurate DTV and RGV. Patients from an earlier period (07/2018-09/2019) before teaching served as controls. The impact of teaching was assessed. Intraoperative detection of DSTP based on fluoroscopy was documented. DTV and RGV were further evaluated as a set of fluoroscopic investigations and not as individual views. The accuracy of DTV and RGV to detect DSTP was compared with that of postoperative ultrasound. Results: A total of 124 patients were included in the study group and compared with the control group (n = 125). Interobserver agreement for the image accuracy was 97% for DTV and 98% for RGV, respectively. Correct images were observed for DTV in 81% after standardized teaching versus 58% for the control group and 81% versus 53% for RGV, respectively ( Conclusions: Standardized teaching leads to a significant improvement of appropriate views. DTV and RGV are reliable tools to detect DSTP. However, some minor dorsal cortex penetrations may be missed. Type of study/level of evidence: Diagnostic IIb.
