Factors predict prolonged colonoscopy before the procedure: prospective registry study.
Observational study in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07228715 (A Study on a New Indicator for Assessing the Difficulty of Colonoscopy Insertion and Its Related Factors), which is not on this map. Cited by 4 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.

Abstract
backgroundColonoscopy difficulty and procedure time can vary between cases, posing challenges for daily scheduling in endoscopy units. In the literature, cecal intubation time (CIT) is commonly used to assess colonoscopy difficulty, yet there is debate regarding the factors influencing CIT. This prospective observational study aimed to evaluate the factors influencing CIT.
methodsIn this single-center, prospective, observational study, 915 patients who underwent colonoscopy between July 2023 and April 2024 were evaluated. Failure to achieve cecal intubation due to poor bowel preparation and a history of colorectal surgery were considered as exclusion criteria. Patients with a CIT ≥ 11 min or those with technically failed cecal intubation were categorized into the prolonged CIT subgroup, while those with a CIT < 11 min were analyzed in the normal CIT subgroup. Patients were evaluated based on demographic characteristics, clinical parameters, and colonoscopy results.
resultsA total of 902 patients included in the final analysis. The median age was 55 years and 55.4% of them were women. The cecal intubation rate was 97.5% (892 patients). The polyp, adenoma, and malignancy detection rate were 27.4, 20.7, and 1.9%, respectively. Median cecal intubation time (CIT) was 6 min (Interquartile range: 4-8). In multivariate analysis, body mass index ≤ 18.5, previous abdominal surgery, increased Wexner Constipation Score, and lesser endoscopist experience were associated with prolonged CIT.
conclusionsBMI, previous abdominal surgery, severity of constipation, and the experience of endoscopist may affect CIT. Considering these factors during daily planning in the endoscopy unit can lead to more efficient facility utilization.
