Kaplan-Meier survival curves for disease-free survival and overall survival. A, B: Kaplan-Meier survival curves overlapped according to the five histological subtypes of invasive lung adenocarcinoma. C, D: Solid-predominant subtype was associated with shorter disease-free survival (P = 0.003) and overall survival (P = 0.014) compared with non-solid predominant subtype. E, F: High-expression of IMP3 was associated with worse disease-free survival (P = 0.039) and overall survival (P = 0.029) in lung adenocarcinoma.
