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

aimDespite lung cancer's high mortality rate, many countries still lack organized lung cancer screening programs. This review aims to evaluate the impact of low-dose computed tomography (LDCT) screening on lung cancer diagnosis, mortality, and overall clinical outcomes. MATERIALS AND

methodsFollowing the Joanna Briggs Institute methodology for umbrella reviews, a comprehensive search was conducted in PubMed, Embase, and the Cochrane Library for reviews published between January 2013 and December 2023. Eligible meta-analyses included studies comparing LDCT screening with chest X-ray (CXR) or no screening, reporting outcomes such as sensitivity, specificity, and lung cancer mortality. The methodological quality of the included reviews was assessed using AMSTAR-2.

resultsOut of 801 citations, 14 meta-analyses met the inclusion criteria. LDCT demonstrated high sensitivity (0.97, 95% CI: 0.94-0.98) and specificity (0.87, 95% CI: 0.82-0.91). It significantly increased early-stage lung cancer detection (RR: 1.31, 95% CI: 1.18-1.45) and reduced lung cancer mortality by 18% (RR: 0.82, 95% CI: 0.75-0.90). However, the reduction in all-cause mortality (RR: 0.91, 95% CI: 0.75-1.06) was not statistically significant. Overdiagnosis and false positives remain essential challenges.

conclusionThis umbrella review confirms that LDCT screening effectively reduces lung cancer mortality, particularly in high-risk populations.
