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

purposeThis study analyzed nationwide trends in lung cancer surgery in South Korea over 14 years, focusing on surgical volume, patient demographics, surgical approaches, and outcomes. MATERIALS AND

methodsWe performed a retrospective cohort study using nationwide health insurance claims data (124,334 cases) and robotic surgery data (1,740 cases) provided by the manufacturer. Patients who underwent lung cancer surgery between 2010 and 2023 were included. Annual trends were assessed using the annual percentage change (APC), and logistic as well as linear regression models were used to identify predictors of mortality and prolonged hospital stay.

resultsThe annual surgical volume increased from 4,557 in 2010 to 14,184 in 2023 (APC, 8.86%; p < 0.001). Video-assisted thoracoscopic surgery (VATS) became the predominant approach, rising from 52.9% to 94.8% (APC, 4.11%; p < 0.001). Sub-lobar resections increased, with wedge resections growing from 9.0% to 18.5% (APC, 5.72%; p < 0.001) and segmentectomies from 3.0% to 17.9% (APC, 14.63%; p < 0.001). The proportion of female patients increased from 32.0% to 44.7% (APC, 2.39%; p < 0.001), while patients aged 70-79 years increased from 26.3% to 32.3% (APC, 1.60%; p < 0.001) and those aged ≥ 80 years from 2.0% to 6.2% (APC, 9.63%; p < 0.001). The median hospital stay decreased from 13 to 7 days (APC, -4.34%; p < 0.001), and 30-day mortality declined from 2.45% to 0.76% (APC, -8.32%; p < 0.001).

conclusionLung cancer surgery in Korea has increased substantially, with a notable shift toward minimally invasive and lung-sparing techniques that have improved outcomes. However, persistent disparities underscore the need for a national surgical registry.
