Correlation of miR-29c and miR-223 expression with other prognostic factors. The mean miR-29c and miR-223 levels measured by qPCR were plotted with their SEM according to Binet stages (A,L), untreated/treated patients (B,M), alive/dead patients (C,N), LDT (D,O), sCD23 (E,P), β2-M (F,Q), IgVH mutational status (G,R), ZAP70 (H,S), LPL (I,T), CD38 (J,U), cytogenetic abnormalities (K,V). miR values are expressed in fold of target miR expression in the calibrator cell line (Namalwa). Statistical differences were assessed using the Kruskal-Wallis test for Binet stages, and the Mann-Whitney nonparametric test was used for other variables. Statistical details can be found in Table 1.
