All intercepts were non-significant and have been removed for clarity. R2, amount of total variance explained; adj., R2 adjusted for the number of predictors; est., estimated coefficient for the variable. t, coefficient divided by its standard error; p, probability value, with asterisk codes for degree of significance: ***p < 0.001; **p < 0.01; *p < 0.05; ß, standardized beta coefficient.
