[Role of radiology for primary staging of colorectal cancer].
Review in Radiologie (Heidelberg, Germany), 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
backgroundImaging, specifically magnetic resonance imaging (MRI), has long been the cornerstone for staging rectal cancer. In contrast, computed tomography (CT) is the standard for colon cancer staging. Primary staging is essential for individualized risk stratification and therapy planning.
objectivesTo summarize current international guidelines on primary colorectal cancer staging, taking into account the advantages and disadvantages of different imaging methods. MATERIALS AND
methodsBased on extensive literature research, the current state of knowledge in the staging of colorectal cancer is summarized.
resultsTNM staging includes local tumor extension as well as the presence of lymph node and distant metastases. For local tumor extension, MRI is very well suited for rectal cancer. In colon cancer, CT shows significant limitations regarding the sensitivity of differentiating individual stages. Lymph node metastases can pose a major challenge for both MRI and CT, which has led to the definition of several malignancy criteria. The detection of distant metastases remains primarily within the domain of CT, except for liver metastases.
conclusionsDepending on tumor location, either MRI or CT is recommended for primary staging of colorectal cancer, and a combination of both modalities may also be appropriate. Accurate assessment of the primary tumor, lymph nodes, and organs using imaging is an essential component of the therapeutic approach to colorectal cancer.
