The R/S values of the CDRs and the FRs plotted against the total number of mutations of individual cases of FLs.

R/S values that amounted to infinite in the CDRs are not shown. The figure shows that R/S values in FRs are consistently low irrespective of the total number of somatic mutations, except for FL no. 59 (R/S ratio of 9; 11 mutations in total). ▪ indicates the R/S value of the CDRs; ○ indicates the R/S value of the FRs.
