Comparison of 0.5-year, 1-year, and 2-year survival between non-CIK group and CIK group. OR, odds ratio; OS, overall survival. non-CIK, non-CIK-containing therapy; CIK, CIK-containing therapy. The random effects meta-analysis model (Mantel-Haenszel method) was used in this analysis. Each trial is represented by a square, the center of which gives the odds ratio for that trial. The size of the square is proportional to the information in that trial. The ends of the horizontal bars denote a 95% CI. The black diamond gives the overall odds ratio for the combined results of all trials. The center denotes the odds ratio, and the extremities denote the 95% CI.
