Radiotherapy combined with third-generation EGFR tyrosine kinase inhibitor in first-line treatment of advanced oligometastatic non-small cell lung cancer: a single-center, retrospective study.

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: Third-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are the standard first-line therapy for advanced EGFR-mutant non-small cell lung cancer (NSCLC). However, disease progression remains inevitable, particularly in the oligometastatic setting. We hypothesized that local radiotherapy (RT) could alter the disease course by eradicating resistant clones. Therefore, this study aimed to evaluate the efficacy of RT combined with a third-generation EGFR-TKI as first-line therapy for advanced oligometastatic NSCLC. Methods: We retrospectively analyzed EGFR-mutant advanced oligometastatic NSCLC patients treated with third-generation EGFR-TKI at Zhejiang Cancer Hospital. Patients were stratified into TKI only group and TKI + RT group. Efficacy and safety were compared across groups. Results: From March 2021 to September 2023, a total of 260 patients were enrolled, including 143 received TKI only group and 117 received TKI + RT group. With the median follow-up of 26.2 months, the median progression-free survival (PFS) was 20.6 and 26.0 months (P=0.18), and the median overall survival (OS) was 45.5 and 52.2 months (P=0.98) for TKI only and TKI + RT group respectively. For the subgroup of delivered biologically effective dose with an α/β ratio of 10 Gy (BED Conclusions: RT (BED
