  1. a Pearson correlation coefficients were calculated for each hematology test over age of the rhesus macaques. P < 0.05 was considered statistically significant.
  2. b Mean values of hematology tests were calculated for animals in the three age groups of rhesus macaques. Student’s t Test was measured to determine statistically significant differences between the older and younger groups of animals. P < 0.05 was considered statistically significant.
  3. c Not significant = n.s.
