Survival in gastric and esophageal cancers in the Nordic countries through a half century.
Article in Cancer medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundGastric cancer (GC) and esophageal cancer (EC) are among the most fatal cancers and improving survival in them is a major clinical challenge. Nordic cancer data were recently released up to year 2019. These data are relevant for long-term survival analysis as they originate from high-quality national cancer registries from countries with practically free access to health care, thus documenting 'real-world' experience for entire populations. PATIENTS/
methodsData were obtained for Danish (DK), Finnish (FI), Norwegian (NO), and Swedish (SE) patients from the NORDCAN database from years 1970 through 2019. Relative 1- and 5-year survival were analyzed, and additionally the difference between 1- and 5-year survival was calculated as a measure of trends between years 1 and 5 after diagnosis.
resultsRelative 1-year survival for Nordic men and women in GC was 30% in period 1970-74 and it increased close to 60%. Early 5-year survival ranged between 10 and 15% and the last figures were over 30% for all women and NO men while survival for other men remain below 30%. Survival in EC was below that in GC, and it reached over 50% for 1-year survival only for NO patients; 5-year survival reached over 20% only for NO women. For both cancers, the difference between 1- and 5-year survival increased with time. Survival was worst among old patients.
conclusionGC and EC survival improved over the 50-year period but the increase in 5-year survival was entirely explained by gains in 1-year survival, which improved at an accelerated pace in EC. The likely reasons for improvements are changes in diagnosis, treatment, and care. The challenges are to push survival past year 1 with attention to old patients. These cancers have a potential for primary prevention through the avoidance of risk factors.
