Comparing survival outcomes of localized tumor destruction, sublobar resection, and pulmonary lobectomy in stage IA non-small cell lung cancer: a study from the SEER database.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeA large-scale comparative analysis was performed with the aim of comparing local tumor destruction (LTD), sublobar resection (SR), and pulmonary lobectomy (PL) for cancer-specific survival (CSS) and overall survival (OS) in stage IA non-small cell lung cancer (NSCLC).
methodsIn the Surveillance, Epidemiology, and End Results (SEER) database (2000-2021), we included patients with pathologically confirmed stage IA non-small cell lung cancer who were treated with LTD, SR, or PL. Comparison between groups was performed separately after 1:1 proportional propensity score matching (PSM) with a caliper value of 0.1. Kaplan-Meier analysis was performed to compare survival outcomes between groups.
resultsIn the total cohort of 4437 LTD patients, 2425 SR patients, and 6386 PL patients, 84.18% of LTD-treated patients were older than 65 years, whereas 68.95% of SR-treated patients and 62.82% of PL-treated patients were older than 65 years. The CSS (HR = 0.756, 95% CI 0.398 ~ 1.436, P = 0.393) and OS (HR = 0.46, 95% CI 0.553 ~ 1.295, P = 0.442) of LTD were consistent with SR. Whereas LTD demonstrated lower CSS (HR = 0.603, 95% CI 0.378 ~ 0.940, P = 0.024) and OS (HR = 0.590, 95% CI 0.432 ~ 0.805, P < 0.001) than PL, but were consistent when the tumor size was ≤ 1 cm. The CSS (HR = 1.215, 95% CI 0.872 ~ 1.693, P = 0.249) of SR was consistent with PL, but OS (HR = 1.347, 95% CI 1.079 ~ 1.681, P = 0.008) was higher than PL, but were consistent when the tumor size was 1.1-3 cm.
conclusionsIn patients with stage IA non-small cell lung cancer, the CSS and OS of LTD were no worse than those of SR. Compared with PL, the CSS and OS of LTD were lower, but when the tumor size was ≤ 1 cm, the CSS and OS of LTD were no worse than those of PL.
