The impact of STAS on paraffin and frozen sections on the prognosis of clinical stage IA small-sized NSCLC. A Kaplan–Meier curves for OS (left panel) and RFS (right panel) curves of patients with STAS-positive and negative on paraffin sections. B Forest plots of OS (upper panel) and RFS (lower panel) of patients with STAS-positive and negative on frozen sections. STAS: tumor spread through air spaces; NSCLC: non-small cell lung cancer; OS: overall survival; RFS: recurrence-free survival; Tdmax: maximum tumour diameter; CTR: consolidation tumor ratio
