SMARCA4 and non-small cell lung carcinoma: In NSCLC patients, multivariate Cox regression analysis showed SMARCA4 status (HR: 0.27; 95% CI: 0.17–0.45), smoking history (HR: 1.72; 95% CI: 1.11–2.66), and invasive tumor size (HR: 1.11; 95% CI: 1.01–1.23) were independent factors affecting the prognosis of NSCLC, as shown in Table S2.
