Bolded p-values are significant after FDR correction.
*Effect of time, for each variable; the differences have been tested between the means of the two arms at different follow-up control.
**Effect of group for each variable; the differences have been tested between the means of web arm in four times (baseline, T3, T6 and lockdown) and the means of the traditional arm at the same four times.
***Probability that the effect of time is greater in one distinct arm (interaction time*arm).
