Public assistance and survival equality in patients with EGFR mutation-positive lung cancer.
Article in Japanese journal of clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgroundDisparities in public assistance or the urbanization level of a residential region can affect cancer treatment outcomes. This study aimed to investigate whether these factors affect the overall survival (OS) of patients with epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC) using Tokushukai REAL World Data.
methodsWe analyzed the clinical data of consecutive patients with NSCLC receiving EGFR-tyrosine kinase inhibitors between April 2010 and March 2020 at 46 Tokushukai Medical Group hospitals in Japan. The patient's insurance coverage status was extracted from electronic medical records, and the urbanization level of residential regions was classified as megalopolis or other according to the secondary medical region. Univariate and multivariate Cox regression analyses were performed to examine the associations between OS and patient/tumor/treatment/socioeconomic-related factors.
resultsIn total, 758 patients (58.5% females) were included in the study; 41 patients (5.4%) received public assistance, and 442 patients (58.3%) were categorized under megalopolis in the secondary medical regions. In multivariate Cox regression analyses, there was no significant difference in the OS between non-recipients of public assistance and recipients [hazard ratio (HR) 1.084; 95% confidence intervals (CIs), 0.674-1.744]. There was also no significant difference in the OS between megalopolis and other regions in the secondary medical regions (HR 1.143; 95% CIs, 0.914-1.428).
conclusionsOur findings suggest that neither the use of public assistance nor the urbanization level in the residential region significantly impacts the prognosis of Japanese patients with EGFR mutation-positive NSCLC.
