rho: Spearman’s Rank correlation coefficient

adjusted p-value: two-tailed with Bonferroni adjustment

df: degrees of freedom

adjusted df: adjusted degrees of freedom

alpha level: directional alpha levels of critical values for Spearman’s Rank correlation coefficient

/not a predictor variable in corresponding time transition

predictor variable with alpha level ≤0.05 is in bold
