Colon capsule endoscopy following incomplete colonoscopy in routine clinical settings.
Trial report in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04307901 (Safety Of ColoRectal Assessment and Tumor Evaluation by Colon Capsule Endoscopy), which is not on this map. Cited by 4 papers, 2 of them syntheses that pooled it.
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

Abstract
backgroundColon capsule endoscopy (CCE) was introduced in our department on two indications; following incomplete colonoscopy as an alternative to CT colonography, and in patients with a history of incomplete colonoscopy as an alternative to anesthesia-assisted (AA) colonoscopy. We aimed to compare the quality of CCE, defined by completion rate and polyp detection rate (PDR), with that of CT colonography and AA colonoscopy, respectively.
methodsPatients referred for CCE from May 2020 until November 2021 were consecutively included in this prospective cohort study. Demographics, indication and CCE outcomes were registered from the electronic patient record. Completion rate and PDR in CCE as an alternative to CT colonography were compared with those of a historical cohort undergoing CT colonography following incomplete colonoscopy. Completion rate and PDR in CCE as an alternative to AA colonoscopy were compared with those of a time true parallel cohort undergoing AA colonoscopy.
resultsIn 65 patients undergoing CCE, 36 (57%) were referred as an alternative to CT colonography. The completion rate in this group was 44% compared to 96% in CT colonography (p < 0.001). The PDR in complete CCE in this group was 75% in CCE compared to 20% in CT colonography (p < 0.001). The remaining 27 (43%) of the sample were referred for CCE as an alternative to AA colonoscopy. The completion rate in this group was 33% compared to 100% in AA colonoscopy (p < 0.001). The PDR in complete CCE in this group was 78% in CCE compared to 35% in AA colonoscopy (p = 0.013).
conclusionsThe completion rate of CCE following incomplete colonoscopy is inferior to that of CT colonography and AA colonoscopy. The PDR of CCE was high, indicating an acceptable sensitivity in complete investigations, but in our settings the completion rate of CCE on this indication is unacceptably low. CLINICAL
