Post-operative colorectal cancer surveillance: preference for optical colonoscopy over computerized tomographic colonography.
Trial report in Cancer causes & control : CCC, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02143115 (Comparative Effectiveness of Virtual and Optical Colonoscopy for Colorectal), which is not on this map. Cited by 3 papers, 1 of them a synthesis 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
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.

Abstract
purposePost-operative surveillance strategies for colorectal cancer (CRC) include periodic optical colonoscopy (OC) and abdominal-pelvic CT scan. Adherence with these recommendations is limited. For CRC screening, CT colonography (CTC) identifies larger adenomas and cancers nearly as well as OC. Most screening studies demonstrate that patients prefer CTC. However, CTC has never been compared to OC in the post-operative surveillance setting.
methodsWe hypothesized that CTC might represent an attractive substitute for the standard OC/CT scan combination. Here, 223 patients underwent CTC followed by same day OC 1 year after curative CRC resection.
resultsOf the 144/223 (64.6%) participants with a preference, 65.9% (95/144) preferred OC. This preference was more pronounced in women and in patients with polyps detected. No additional patient level factors significantly altered this primary result.
conclusionsIn contrast to CRC screening, this first study in CRC post-operative surveillance patients demonstrates a preference for OC. Assuming patient preference is an important determinant, introduction of CTC as a method to increase patient adherence with CRC surveillance is unlikely to be effective.
