The impact of incomplete colonoscopies: a single-centre retrospective study.
Article in Canadian journal of surgery. Journal canadien de chirurgie. 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
backgroundScreening for colorectal cancer reduces mortality by enabling early detection. In Quebec, follow-up within 60 days after an incomplete colonoscopy is recommended. In this study, we sought to assess the impact of delays in follow-up on patient outcomes.
methodsIn this retrospective study, we included adults who underwent a colonoscopy following a positive immunochemical fecal occult blood test at the Centre intégré universitaire de santé et de services sociaux de l'Estrie-Centre hospitalier de l'université de Sherbrooke between Jan. 1, 2013, and Dec. 31, 2015. We verified colonoscopy adequacy and guideline adherence. We classified advanced polyps and colorectal cancer as clinically significant lesions (CSLs) to assess the clinical impact of incomplete or missing follow-up colonoscopies.
resultsIn 89 cases of incomplete colonoscopies, inadequate bowel preparation was the leading cause of exam interruption (61.8%). A total of 57 patients had a subsequent follow-up, and 23 colonoscopies were completed within the 60-day time frame. Six CSLs, including advanced polyps and cancer, were detected within the recommended 60-day time frame, and 4 were identified after 60 days. We found a statistically significant difference in the rates of colorectal cancer diagnosis (
conclusionThe poorer prognosis associated with patients who had a delayed or missing follow-up highlights the importance of respecting provincial guidelines concerning follow-up after incomplete colonoscopies.
