Spearman’s correlation test between MLVD and the overall survival. Spearman’s correlation test indicated that the range 4 to 12 MLVDs is a distinctive range with significant inverse proportion to the overall survival (P <  0.0001). However, the range 13 to 25 showed no significant proportion to the overall survival (P = 0.4791), indicating that all patients involved in this range obtained unfavorable prognosis regardless increase of the MLVD. Patients censored before 5 years of follow-up investigation were not included
