Association of Cancer Care Quality Certification With Survival Across Multiple Cancer Types: A Population-Based Cohort Study in Taiwan.
Article in International journal of 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
Cancer remains a major global health burden. Taiwan launched the Cancer Care Quality Certification (CCQC) program in 2008; however, comprehensive evaluations of its association with survival across multiple cancer types remain limited. A total of 294,323 patients diagnosed with one of eight cancer types between 2011 and 2017 were identified from the Taiwan Cancer Registry Database. Overall survival among patients treated at certified versus non-certified hospitals was compared using Cox proportional hazards models incorporating a hospital-level shared frailty to account for institutional heterogeneity, adjusting for age, sex, stage, hospital level, geographic region, and treatment modalities. Treatment at certified hospitals was associated with lower all-cause mortality for colorectal (adjusted hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.83-0.93), lung (HR, 0.91; 95% CI, 0.87-0.96), and bladder cancers (HR, 0.79; 95% CI, 0.66-0.96). No statistically significant associations were observed for liver, female breast, cervical, uterine, or ovarian cancers. In this population-based study, the CCQC program in Taiwan is associated with improved survival for several major cancers, although the magnitude of association varied by cancer type. These findings suggest that certification may serve as a marker of institutional capacity for delivering high-quality cancer care and support the continued evaluation of certification programs as a potential strategy for strengthening cancer care systems.
