Risk factors for radiation pneumonitis in NSCLC patients treated with third-generation EGFR TKIs and chest radiotherapy.

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
backgroundNon-small cell lung cancer (NSCLC) patients receiving third-generation EGFR TKIs with thoracic radiotherapy (TRT) significantly prolong survival and also increase the incidence of radiation pneumonitis (RP). The aim of our study was to investigate the incidence and risk factors of RP in NSCLC patients receiving third-generation EGFR TKIs and TRT. PATIENTS AND
methodsWe retrospectively evaluated NSCLC patients who received both third-generation EGFR TKIs and TRT at the General Hospital of Ningxia Medical University from January 2023 to September 2024. RP was diagnosed by clinical symptoms on computed tomography (CT) scans and graded according to the Common Terminology Criteria for Adverse Events 5.0. Risk factors for RP were determined by univariate and multivariate logistic regression analysis.
resultsOf the 42 patients included, 26 (61.9%) developed RP and 14 (33.3%) developed grade ≥ 2 RP. Grade ≥ 2 RP all occurred within 6 months of receiving TRT, and the median time from TRT to RP was 3.69 months (2-10 months). GTV ≥ 39 ml and total lung V20 ≥ 14.95% were found to be independent risk factors for RP development.
conclusionThe strategy of combining a third-generation TKI with TRT significantly increases the incidence of RP, and the risk of RP in these patients can be reduced by adjusting lung radiation dosimetry parameters. In NSCLC patients taking triple-generation TKIs with primary tumour progression, the timing and dose of TRT addition must be strictly controlled to optimise the therapeutic strategy and reduce the incidence of RP.
