Factors behind favorable long-term lung cancer survival in Norway compared to Denmark: a retrospective cohort study.
Article in European clinical respiratory journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Long-term survival of patients with non-small cell lung cancer (NSCLC) is considerably higher in Norway compared to Denmark, even though diagnostic work-up, treatment, and follow-up are comparable. We aim to explore factors behind favorable long-term survival for lung cancer patients in Norway compared to Denmark. Method: A retrospective cohort study of patients with NSCLC diagnosed between 2014 and 2016. From the Danish Lung Cancer Registry, 1000 patients were randomly selected, and 974 patients were included. From the Norwegian Vestfold Hospital Trust, 220 patients were randomly selected, and 218 were included. Data from medical records were obtained for all patients. The Danish and Norwegian cohorts were compared using the Pearson chi squared test and multivariate logistic regression analysis. Results: The two cohorts were comparable in terms of age, sex, and smoking history. However, the Danish patients had a higher number of pack-years (43.5 vs 34.5 Conclusions: We found a higher proportion of Norwegian patients diagnosed at potential curable stage and fewer heavy smokers compared to Danish patients. This could contribute to the superior long-term survival found in Norwegian NSCLC patients.
