Evaluation of OS with high or low abundance of CTCs by using meta-analysis (a-c) and systematic review (d). a. Higher abundance of CTCs had not significant predict power of prognosis of lung cancer cases. b Stratified analysis showed the differences of tumor stages in different cohorts lead to heterogeneity(I2 = 81.5%). c Stratified analysis showed various detect methods in different cohorts lead to heterogeneity (I2 = 79.0%). d Systematic review of OS (months) data indicated higher abundance of CTCs are associated with shorter OS
