Global quality of care trends for lip and oral cavity cancer: A quality of care index analysis, 1990-2021.
Article in Preventive medicine reports, 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
Objective: To evaluate global trends and disparities in the quality of care for lip and oral cavity cancer (LOCC) from 1990 to 2021 using the Quality of Care Index (QCI). Methods: Data on LOCC burden were obtained from the Global Burden of Disease (GBD) 2021 study, covering 204 countries and territories from 1990 to 2021. The QCI was constructed via principal component analysis of four component indices: mortality-to-incidence ratio, prevalence-to-incidence ratio, years of life lost to years lived with disability ratio, and disability-adjusted life years to prevalence ratio. Analyses were stratified by socio-demographic index (SDI), age, and sex. Results: A geographical decoupling was observed: high-SDI regions had the highest LOCC incidence, while low-middle SDI regions had the highest mortality. The global QCI improved from 1990 to 2021 but strongly correlated with national development. Females consistently had higher QCI scores than males across all SDI groups. The QCI-age relationship varied by SDI region. Conclusions: Despite global improvement, significant inequities in LOCC care quality persist across regions, ages, and sexes. Future strategies must focus on enhancing healthcare system performance and ensuring equitable access to effective care.
