First column shows, in italics, dependent values for each regression model. Beta-values (±bootstrapped standard errors) are shown, together with 95% confidence intervals (CIs) and bootstrapped p values. Only regressors significant at ^∗ p < 0.05 and ^(∗) p < 0.1 are presented here (see Supplemental Table 1 for full results of regression analyses). ^†Self-practice regressors are coded against a reference of no yoga self-practise. ^‡Note that, due to regression-to-the-mean phenomena, any relationship specifically between baseline psychometrics and key dependent variables should be interpreted with care (see also main text).
