Residential location shapes initial prostate cancer care in Korea (2010-2020): A nationwide stage- and risk-stratified study.
Article in Investigative and clinical urology, 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
purposeTo characterize nationwide patterns of initial prostate cancer (PCa) management in Korea from 2010 to 2020, stratified by clinical stage, risk, and residential context. MATERIALS AND
methodsWe performed a secondary analysis of a chart-abstracted cohort from 51 general hospitals. Initial treatment was classified into ten mutually exclusive categories (active surveillance; surgery; surgery after androgen deprivation therapy [ADT]; radiotherapy; radiotherapy after ADT; docetaxel after ADT; androgen receptor-targeted agent [ARTA] after ADT; ADT-only ≥1 year; other active treatment; unknown). Localized disease (T1-T4N0M0) was stratified by risk (low, intermediate, and high). Residential context was coded as capital versus non-capital and urban versus rural. National Comprehensive Cancer Network risk stratification (version 2.2024) was applied uniformly across survey years.
resultsAmong 27,075 men, initial management differed significantly by stage, risk, and residence. In localized disease, surgery predominated, active surveillance was most frequent in low-risk disease, and radiotherapy and ADT-only increased with higher risk (p<0.001). Over time, ADT-only decreased in metastatic disease, with increases in radiotherapy and systemic intensification (p=0.004). Capital and urban residence were associated with greater use of surgery in localized disease and systemic intensification in metastatic disease, whereas non-capital and rural residence relied more on ADT-only (all p<0.001). In multivariable analyses, residential context remained independently associated with treatment selection after adjustment for age, prostate-specific antigen, grade, and stage.
conclusionsInitial PCa management in Korea during the 2010s reflected contemporary adoption of surgical and systemic therapies but demonstrated persistent geographic variation, indicating residential context influences real-world access to guideline-concordant care.
