a Correlation between CFU-fs/mL and total nucleated cells/mL in bone marrow aspirates harvested using the SSLM method. Because the data were not normally distributed, the Spearman’s rank-order correlation test was used. The Spearman coefficient was 0.4848, indicating a positive correlation between the two variables that was significant (p = 0.0062). b Correlation between CFU-fs/mL and age in bone marrow aspirates harvested using the SSLM method. Because the data were normally distributed, the Pearson’s correlation test was used. The Pearson correlation coefficient was − 0.4689, indicating a negative correlation between the two variables that was significant (p = 0.009)
