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
backgroundDigitally Enhanced Hands-on Surgical Training (DEHST) platform was introduced to overcome the lack of training capabilities for the challenging task of freehand distal interlocking of intramedullary nails. It demonstrates high perceived realism for surgeons, and novices perform significantly better after DEHST training. However, characterization of how performance improves remained unexplored. The aim of this study was to evaluate the training progression of novices in freehand distal interlocking during five training rounds with DEHST and to compare their performance in a simulated operation against experienced surgeons.
methodsTen novices (Group 1) underwent five DEHST training sessions (approximately one hour in total) and their performance data was acquired and evaluated. The surgical performance of Group 1 was compared with ten surgical experts (Group 2) by performing distal interlocking of a real tibia nail in an artificial bone model in a simulated operation. Time taken, number of X-rays, accuracy of nail hole roundness, and success rates were compared between the groups.
resultsGroup 1 achieved comparable performance to Group 2 in number of X-rays 26.0 (range 15-40) versus 22.5 (range 16-34), p = 0.281, and accuracy of hole roundness 95.0% (range 91.1-98.0%) versus 93.3% (range 90.7-95.9%), p = 0.087. However, Group 1 needed significantly longer time compared with Group 2, p = 0.001, and furthermore, one participant in Group 1 (10%) failed to hit the nail hole with the drill bit, while 100% of the participants in Group 2 were successful.
conclusionsDEHST appears to be a useful tool to gradually improve the proficiency level of novices and to train relevant practical surgical skills needed for distal interlocking of intramedullary nails. However, further investigations are needed to demonstrate the performance under the conditions of a real operation.
