Progression-free survival (PFS) and overall survival (OS) according to microvessel density and miRNA expression in tumor tissue.

Footnote: MVD: microvessel density; ADC: lung adenocarcinoma; SCC: squamous cell lung cancer; PFS: progression-free survival; OS: overall survival; NR: not reached due to 1 year observation time; HR: hazard ratio; CI: confidence interval.1Log-rank test;2groups with high/low MVD or high/low expression for selected miRNAs according to cut-off values (median MVD or median relative expression).
