Fig. 3From: Epidemiological features and survival outcomes in patients with malignant pulmonary blastoma: a US population-based analysisCumulative incidence of cause-specific death for PB patients. The cumulative incidence of cause-specific death for (a) overall patients and stratified patients by (b) age at diagnosis, (c) clinical stage, (d) histologic subtype, (e) surgery or not and (f) the number of primary malignancy. The p values for comparison of the cumulative incidence functions according to different stratification are based on Gray’s test (R program, Version 3.6.3, R core team). PB, pulmonary blastoma; PPB, pleuropulmonary blastoma; WDFA, well-differentiated fetal adenocarcinoma; CBPB, classic biphasic PBBack to article page
