MicroRNAs as prognostic biomarkers for survival outcome in osteosarcoma: A meta-analysis

Figure 1 The flow chart of this meta-analysis to identify inclusion studies.

Figure 2 Forest plots for the microRNAs associated with clinical outcome. A: Forest plots for the microRNA (miRNA) associated with overall survival; B: Forest plots for the miRNAs associated with disease-free survival, progression-free survival and recurrence-free survival.

Figure 3 Forest plot of subgroup analysis. A: Subgroup analysis based on microRNA expression; B: Subgroup analysis based on specimen type; C: Subgroup analysis based on survival analysis; D: Subgroup analysis based on source of hazard ratio; E: Subgroup analysis based on follow-up; F: Subgroup analysis based on country of publication.
