qPCR score combining miR-29c, miR-223, ZAP70, and LPL stratifies CLL patients in terms of TFS and OS. TFS, according to our qPCR score, was plotted with Kaplan-Meier methods for all Binet stages (A) and only Binet stage A (E). Tables B and F provide the number of patients and treatment events per subgroup. OS, according to our qPCR score, was plotted with Kaplan-Meier methods for all Binet stages (C) and only Binet stage A (G). Tables D and H provide the number of patients and treatment events per subgroup. The HR was calculated with univariate Cox regression.
