(A) Forest plot of the comparison of ORR and DCR between the experimental and control groups. (B) Funnel plot of ORR. (C) Funnel plot of DCR. Control group, chemotherapy alone group; experimental group, chemotherapy plus DC–CIK immunotherapy. The fixed-effects meta-analysis model (Mantel–Haenszel method) was used.

Abbreviations: CI, confidence interval; DC–CIK, dendritic cells and cytokine-induced killer cells; DCR, disease control rate; IV, inverse variance; M–H, Mantel–Haenszel test; OR, odds ratio; ORR, overall response rate; SE, standard error.
