*1 The total number of participants is reported on the left and the number of repeat participants is reported in brackets. | ||||||
*2 By “well-known” we refer to covariates which have been extensively documented in previous studies. | ||||||
*3 Relevant features are those which increase or reduce contact intensity by more than 5% relative to the baseline. | ||||||
*4 Relevant features are those which reduce contact intensity by more than 5% relative to the baseline. | ||||||
