1 · What the graph read from it

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.

2 · The registry

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

aimLung cancer is the leading cause of cancer deaths worldwide. This study examines the current and future burden of lung cancer at global, regional, and national levels.

methodsThe estimates of lung cancer incident cases, deaths, and their age-standardized rates are drawn from GLOBOCAN 2020 for 21 regions and 185 countries. Mortality-to-incidence ratio (MIR) is considered as a proxy indicator of 5-year survival rates. Lung cancer burden in 2050 is projected using age-specific incidence and death rates in 2020.

resultsIn 2020, there were 2.21 million new cases and 1.8 million deaths due to lung cancer worldwide with age-standardized incidence rate (ASIR) of 22.4/100,000 (male: 31.5; female: 14.6) and age-standardized mortality rates (ASMR) of 18.0/100,000, (male: 25.9; female: 11.2/100,000). Global MIR of lung cancer was 0.82 (males 0.83; females: 0.79), varying from 0.59 (Japan) to 1.0 (Belize). Hungary had the highest age-standardized rates (ASIR: 50.1/100,000; ASMR: 42.4/100,000) and Nigeria (ASIR: 0.88; ASMR: 0.86) had the lowest age-standardized rates in 2020. Both ASIR and ASMR were positively correlated with country-level tobacco smoking prevalence and human development index (HDI), whereas MIR exhibited a negative correlation with HDI. As per our projections, there will be 3.8 million incident cases and 3.2 million deaths globally due to lung cancer in 2050.

conclusionWith close to 2 million cases and deaths already in 2020, lung cancer has already become a global public health threat. Even with current risk levels and age-specific rates, lung cancer annual cases are expected to reach 3.8 million in 2050. Until smoking prevalence is reduced and ambient air pollution levels are checked, particularly in low/medium HDI countries, the lung cancer epidemic will continue unfolding.
