Routes to cancer diagnosis for migrants in Denmark: a population-based nationwide cohort study.
Article in BMC cancer, 2026. 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
backgroundMigrants are often diagnosed with cancer at more advanced stages than the background population, resulting in poorer prognosis. The route to cancer diagnosis is associated with the prognosis, but little is known about the diagnostic pathways for migrants. This study aimed to describe the routes to diagnosis (RtD) for migrants in Denmark and compare these with the RtD for patients of Danish origin.
methodsWe conducted a nationwide cohort study based on Danish registry data, including patients aged ≥ 18 years who were diagnosed with incident cancer between 2014 and 2018 (n = 154,647, including 8066 migrants). Using the UN M49 Standard, we categorised the study population into 15 groups based on country or region of origin (defined according to parental birth country or citizenship), including 14 migrant groups and a reference group of Danish origin. Each patient was assigned to one of six specified RtD. Using multinomial logistic regression models, we assessed associations between migrant groups and RtD.
resultsA total of 44.5% of all cancer patients were diagnosed through a primary care cancer patient pathway (CPP), with variations across migrant groups. Compared with patients of Danish origin, a higher risk of diagnosis via an unplanned hospital admission relative to a CPP from primary care was seen for migrants from the former Yugoslavia (relative risk ratio (RRR) 1.30, 95% CI 1.06–1.60), Germany (RRR 1.34, 95% CI 1.12–1.59), Western Asia (RRR 1.61, 95% CI 1.28–2.02), Türkiye (RRR 1.67, 95% CI 1.29–2.15) and Africa (2.02, 95% CI 1.58–2.60).
conclusionsSome migrant groups experienced higher diagnosis rates via unplanned hospital admission compared with patients of Danish origin, which could impact their prognosis. The results underline the importance of strengthening cancer diagnostic pathways for migrant populations.
