Chronic Obstructive Pulmonary Disease-Associated Mortality - China, 2014-2021.
Article in China CDC weekly, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Introduction: China faces a growing burden of chronic obstructive pulmonary disease (COPD). Previous mortality estimations were primarily based on the underlying cause of death. This study analyzed COPD-associated death and its comorbidities using all COPD cases listed on the chain of events on death certificates. Methods: A retrospective analysis of the National Mortality Surveillance System (NMSS) was conducted to estimate COPD-associated mortality from 2014 to 2021. Age-standardized mortality rates (ASMRs) were calculated stratified by sex, region, and residence. Joinpoint regression was used to estimate the average annual percentage change (AAPC) during the study period. Results: From 2014 to 2021, the ASMR of COPD decreased from 91.85 to 45.90 per 100,000 population. Significant but uneven decreases in COPD mortality were observed across gender [females: AAPC: -11.2%, 95% confidence interval ( Conclusions: COPD is a significant comorbidity of other disorders in China. Although COPD-associated mortality substantially decreased from 2014 to 2021, the burden remained high in underdeveloped regions.
