Phase-specific learning curves in robot-assisted rectal surgery: implications for surgical training.
Article in International journal of colorectal disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTechniques for abdominal and pelvic manipulation vary in robot-assisted rectal surgery (RRS); thus, differences in the learning period between these two phases remain unclear.
methodsThis retrospective single-center study included 75 patients diagnosed with rectal malignancy who underwent RRS from September 2019 to May 2024. The cumulative sum method was used to analyze the learning curve and compare between abdominal and pelvic phases.
resultsThe learning curve for the total console time consisted of three phases: I (learning phase, cases 1-25), II (consolidation phase, cases 26-55), and III (maturing phase, cases 56-71). The learning curve for the abdominal phase involved two phases: I (learning phase, cases 1-23) and II (maturing phase, cases 24-71), with no consolidation phase observed. Conversely, in the pelvic phase, the learning phase was achieved in 27 cases, followed by the consolidation phase in 32 cases (cases 28-59) and the maturing phase in the last 16 cases (cases 60-75).
conclusionsThe learning period during RRS was shorter for the abdominal manipulation than for the pelvic manipulation, considering the absence of the consolidation phase. Education and training that consider these points may be useful for the more efficient learning of RRS.
