Learning curve of consolers and bedside surgeons fused robotic-assisted thoracoscopic segmentectomy: insights from the initial 100 cases.
Article in Surgery today, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThis study examined the learning curve of segmentectomy using the "fused surgery" approach.
methodsWe retrospectively collected data from 100 patients who underwent segmentectomy via fused robot-assisted thoracoscopy at our institution between September 2020 and February 2024. The learning curve was evaluated using the cumulative sum of the operative times in all cases and was analyzed separately for simple and complex segmentectomies.
resultsAfter applying the cumulative sum method to all cases, we obtained a graph of the operative time that showed three well-differentiated phases: phase 1 (n = 23), the initial learning phase; phase 2 (n = 28), the increased competence phase; and phase 3 (n = 49), the highest skill phase. Comparing phases 1 and 2 with phase 3, we found significant differences in operative time (P < 0.001); however, no significant differences were observed in bleeding or rate of postoperative complications. We observed a significant reduction in operative time after 25 simple segmentectomies and 22 complex segmentectomies.
conclusionsThe data suggested that the inflection point of the learning curve was achieved in 51 cases. Complex segmentectomy requires the same cases to achieve the same level of competence as simple segmentectomy.
