Prospective assessment of learning curve and impact of intensive versus progressive training in colonoscopy competence among French residents.
Article in BMC medical education, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundsThere are no existing data in the literature on the learning curve of French interns in colonoscopy or on the comparison between different frequencies of colonoscopy training modalities. We aimed to assess the number of procedures required for French residents in hepatogastroenterology to achieve competency in colonoscopy.
methodsThe primary outcome was achieving greater than 90% cecal intubation rate (CIR90) competency using the Learning Curve-Cumulative Summation (LC-CUSUM) method. Participants with over 80 procedures were categorized into intensive and progressive training groups. We compared the proportion of residents reaching competency, the number of colonoscopies to reach it, and the speed of competency.
resultsThe study included 81 residents, totaling 6,259 procedures. 29 did more than 80 procedures: 12 in the progressive group and 17 in the intensive group. 204 colonoscopies were needed for reaching CIR90 competency (21% of residents). Achievement rates were similar across groups: 50% in the progressive and 65% in the intensive group (p = 0.50). LC competency was reached by 8.6% of residents after an average of 225 procedures, with no significant difference between groups (p = 0.21). Survival analysis showed no significant difference in the speed of competency acquisition between groups (p = 0.77 and p = 0.14, respectively). The Polyp Detection Rate (PDR) averaged 40%.
conclusionGiven that only 21% reached CIR90, efforts are needed to increase the number of colonoscopies during training. CLINICAL TRIAL NUMBER: Not applicable.
