In non-hematological malignancy, meta-regression analysis revealed that cancer stage ( P = 0.004) and cutoff for LMR ( P = 0.015) might be significant contributors to heterogeneity, whereas publication year, publication type, study design, type of cancer, ROC curve and analysis of hazard ratio were not ( P = 0.250–0.950).
