International Trends in Head and Neck Cancer Mortality.
Observational study in JAMA otolaryngology-- head & neck surgery, 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
Importance: Head and neck cancer (HNC) accounts for nearly 1 million new cases and approximately half a million deaths annually worldwide, representing a substantial global health burden. Despite an overall decline in mortality in many regions, patterns vary across anatomical subsites and countries. Objective: To evaluate international and national mortality trends in HNC and its major anatomical subsites from 2001 to 2023. Design, Setting, and Participants: This observational epidemiologic study analyzed population-based mortality data from the World Health Organization (WHO) Mortality Database for 73 countries between 2001 and 2023. Data collection was conducted in May 2025, and the data were analyzed between May and October 2025. Eligible countries had medium- to high-quality vital registration data. Age-standardized mortality rates (ASRs) were calculated using the new WHO World Standard Population. Country-specific trends from 2010 to 2023 were assessed using joinpoint regression among countries with at least 7 years of available data. Main Outcomes and Measures: ASRs and average annual percentage change in HNC mortality overall and by anatomical subsite using population-based analysis. Results: From 2001 to 2023, 2 000 066 HNC-related deaths (450 657 females; 1 549 409 males) were recorded. Internationally, ASRs decreased by 38.9%, with greater reductions among male individuals than among female individuals. Substantial divergence was observed across subsites: laryngeal cancer mortality decreased markedly (-50.1%), whereas increasing trends in oropharyngeal cancer mortality were observed in many countries in recent years, particularly in high-income countries such as the UK (average annual percentage change, 4.30%) and the US (average annual percentage change, 3.26%). Conclusions and Relevance: Results of this study suggest that, although overall HNC-related ASRs have declined internationally, marked variation across subsites and countries persists. The contrasting trends between laryngeal and oropharyngeal cancers underscore the need for subtype-specific prevention strategies and continued global surveillance.
