Video Killed the Radio Star-A Meta-Analysis on Video-Based Coaching to Improve Surgical Skill.
Synthesis in World journal of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 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
backgroundThe surgical trainee of today completes their postgraduate training with significantly less exposure than their mentors. The enforced reduced working hours, along with other factors, have created a gap in surgical training. Video-based coaching (VBC) provides an opportunity to improve the surgical technical skill without needing to increase surgical volume. The aim on this study is to investigate the effect of VBC on the surgical technical skill.
methodsA systematic review of randomized controlled trials was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Bias was assessed for using The Cochrane Collaboration's tool for assessing risk of bias. The study was prospectively registered in the Open Science Framework (https://osf.io/sp8rb). Multiple subgroup analyses and meta-analyses were carried out, with results reported as standardized mean differences (SMDs) in performance scores and presented as forest plots.
resultsA total of 15 studies comprising 382 participants were included in the final analysis. From these 15 studies, 201 participants received VBC following a range of surgical procedures. On meta-analyses, the average performance scores for VBC were significantly higher than the controls (SMD 0.71, 95% CI 0.37, 1.04, Z = 4.15, and p < 0.0001) as were the average change scores from baseline to final performance (SMD 0.98 [95% CI 0.61, 1.35, Z = 5.19, and p < 0.0001]). Furthermore, the overwhelming majority of VBC participants across the studies found VBC to a be useful training tool.
conclusionsThis review represents the most comprehensive assessment of the impact of VBC in surgery and demonstrates it to be an effective training tool in improving surgical technical skill acquisition. Training bodies around the world should now look at how best to formally integrate VBC into conventional surgical training.
