Utilization of Computed Tomography Colonography (CTC) at a District General Hospital: A Retrospective Analysis.
Article in Cureus, 2025. 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
Colorectal cancer (CRC) is one of the most common cancers worldwide, necessitating efficient diagnostic pathways. While colonoscopy remains the gold standard, computed tomography colonography (CTC) offers a non-invasive alternative, particularly for elderly and comorbid patients. This retrospective study, conducted at a UK district general hospital (DGH), evaluated patterns of CTC utilization among patients referred for colonic investigations over a 12-month period. Despite CTC's high diagnostic accuracy (93% sensitivity for polyps > 10 mm) and its suitability for high-risk populations, it was used as a first-line investigation in only 3.5% of cases, markedly lower than the 12%-15% reported in tertiary centers. Contributing factors included limited radiologist training, restricted CT scanner capacity, and a prevailing institutional preference for colonoscopy. Addressing these DGH-specific barriers, such as resource constraints and workforce limitations, is critical to enhancing CTC's role within the two-week-wait (2WW) pathway. This study underscores the need for multicenter research to validate these findings and guide policy development, ensuring equitable access to non-invasive diagnostics for frail, comorbid, or preference-driven populations.
