Table 1. Characteristics of the studied groups
Note: RBM — red bone marrow, M — mean; SE — standard error; n — number of people; (min–max) — range of values.
Table 2. Characteristics of the used oligonucleotides
Note: F — forward primer; R — reverse primer; Ta — annealing temperature.
Table 3. Cases of methylation of CpG islands of the promoter regions of BAX, MDM2, TP53, NFkB1 in the study sample
Note: р — is the level of statistical significance of differences between groups, as given by Fisher's exact test.
Table 4. Spearman's rank correlation coefficients (R), dependence of the degree of methylation of the studied gene promoter regions on RBM dose and patient's age at the time of the study. The p-value for Spearman's correlation coefficients is given in parentheses
