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: Personalized management of stage IV lung cancer requires a deeper understanding of metastatic patterns and the potential benefits of localized treatments for each histologic type. This study aims to identify patterns of both intrathoracic and extrathoracic metastases across various histologic types of lung cancer using a nationwide Korean lung cancer database. Methods: The study analyzed data from patients diagnosed with lung cancer between 2014 and 2019, sourced from the Korean Association of Lung Cancer Registry (KALC-R). Patients with stage IV lung cancer, indicated by M staging, were included to focus on metastatic patterns. Results: The cohort included 7,562 stage IV lung cancer patients, with adenocarcinoma being the most prevalent histologic type, comprising 49.22% of cases (3,722 patients). M stage categorization showed that 27.3% were M1a, 56.3% M1b, 15.7% M1c, and 0.6% unspecified. The adenosquamous type had the highest proportion of patients with metastases in three or more organs (42.9%). Metastases to the liver and bones were consistently associated with decreased survival across histologic types. In adenocarcinoma, strong associations were observed between extrathoracic metastatic sites, particularly between bone and liver [odds ratio (OR) =3.93] and liver and adrenal glands (OR =2.85). Multivariate analysis revealed that patients receiving radiotherapy to lung lesions had significantly better overall survival (OS) [hazard ratio (HR) =0.68; 95% confidence interval (CI): 0.60-0.78; P<0.001] compared to those who did not. Radiotherapy to extrathoracic metastases also significantly improved survival (HR =0.84; 95% CI: 0.77-0.93; P<0.001). Conclusions: Understanding metastasis patterns and treatment options specific to each lung cancer histologic type is essential for improving treatment strategies.
