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

backgroundLung cancer is a major cause of death. Japan has a higher rate of early detection of lung cancer, which is attributed to the impact of chest X-ray examinations implemented as mass screening. This study describes the characteristics and outcomes of patients with lung cancer in Japan, where chest X-ray screening is recommended for everyone aged >40 years old.

methodsThis observational study linked the Kyoto City Integrated Database with data from a nationwide cancer registry in Japan. This study assessed individuals aged ≥65 years diagnosed with primary lung cancer between 2014 and 2018. Patients were categorized into the screened or unscreened groups based on their screening history within 1 year before diagnosis.

resultsOf 4473 patients with lung cancer, 231 were included in the screened group. The screened group had a mortality rate of 25% at 1.7 years and 50% at 5.6 years, versus 25% at 0.5 years and 50% at 1.8 years for the unscreened group.

conclusionsPatients with primary lung cancer who underwent lung cancer screening had longer survival and better overall health at diagnosis than those who did not undergo screening. Further study is required to estimate the effectiveness of chest X-ray lung cancer screening.
