OR, odds ratio; CI, confidence interval;
p-value was obtained by logistic regression analysis, taking reference to female, B-lineage, L2, 1–10 years, <50,000 leukocytes/mm3 (low-risk) and downregulated levels of miR-24.
p-value was obtained by multivariate logistic regression analysis.
Significant p<0.05, ALL, acute lymphoblastic leukemia.
