Fragmentation of care and colorectal cancer survival in South Korea: comparisons according to treatment at multiple hospitals.
Article in Journal of cancer research and clinical oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeFragmented cancer care (FC) means that patients visit multiple providers for treatment, which is common in cancer care. While FC is associated with poor health outcomes in patients with colorectal cancer (CRC) worldwide, there is still a lack of evidence in South Korea. We investigated the association between FC and 5-year morality in patients with CRC using population-based claims data.
methodsThe study population was followed up from 2002 to 2015. Data were collected from Korea National Health Insurance claims. Participants comprised patients with CRC diagnosed with International Classification of Diseases (ICD)-10 (C18.x-C20.x) and a special claim code for cancer (V193). Data were analyzed using the Kaplan-Meier curve with a log-rank test and Cox proportional hazard model. The effect of FC on patients' 5-year survival was examined.
resultsOf 3467 patients with CRC, 20.0% had experienced FC. FC was significantly associated with an increased risk of 5-year mortality (hazard ratio 1.516, 95% confidence interval 1.274-1.804). FC was prevalent in those who had a low income level, underwent chemotherapy, did not undergo radiation therapy, and did not visit a tertiary hospital for their first treatment.
conclusionEfforts to decrease FC and integrate complex cancer care within appropriate healthcare delivery systems may improve survivorship among patients with CRC.
