The potential high-risk population for lung cancer screening: determination of initial screening age and heterogeneity in histology and sex.

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
Background: In 2021, the US Preventive Services Task Force expanded the initial age for lung cancer screening from 55 to 50 years, which other associations have not followed. The objective of this study was to evaluate the beneficiary age range for lung cancer screening and assess the potential heterogeneity in tumor histology and patient sex. Methods: Using the Surveillance, Epidemiology, and End Results database, patients with non-small cell lung cancer (NSCLC) between 2011 and 2016 were included. The estimation of overall survival (OS) and lung cancer-specific survival (LCSS) was conducted for survival analysis among three different age groups: 45-49 (n=4,203), 50-54 (n=10,126), and 55-59 years (n=17,122), adjusting for other clinicopathological characteristics. Results: Significant differences were observed in OS {hazard ratio (HR) [95% confidence interval (CI)]: 0.94 (0.92-0.96)} and LCSS [HR (95% CI): 0.94 (0.91-0.97)] for patients aged 50-54 compared to those aged 55-59. However, no survival advantage was observed for patients aged 45-49 [HR (95% CI) for OS: 0.97 (0.93-1.01), HR (95% CI) for LCSS: 0.98 (0.93-1.02)]. Similar survival trends were observed in patients with adenocarcinoma whereas no difference among those with squamous cell carcinoma across all age groups. Among patients aged 40-45, we observed a significant survival advantage for males, with no corresponding advantage in females. Conclusions: Patients aged 50 to 54 can benefit from lung cancer screening, in accordance with the recommendations of the US Preventive Services Task Force (USPSTF). The benefits are probably more apparent in adenocarcinoma cases. Younger male patients may benefit more than female patients, which may reflect the need for sex differences in cancer screening.
