Note: All variables are presented as means (±SD). Statistical significance for the main effect was assessed using ANCOVA controlling for maturity offset. Bonferroni (Dunn) t-test was used to assess differences between groups. Cohen’s d was used to calculate the effect size between the low and high CRF groups
