  1. The number of leukocytes and NK cell percentages were correlated to dose received and volume of irradiated bone marrow (n = 37)
  2. *Required sample size for the obtained correlation coefficients (for α = 0.05 and power of the test β = 0.80) was calculated 32-34 patients
  3. †Statistically significant results are marked in bold
