1Means were estimated by the model.
2P-values multiplied by 2 to adjust for multiple testing (Bonferroni).
3The mean difference between periods was calculated by subtracting the effect in the pre-intervention period from the effect in the intervention period.
4Calculated based on the model estimated mean difference between effect is intervention and pre-intervention period divided by the square root of the variance between participants (intercept).
∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001.
