  1. Statistics mentioning “(pp)” are “per patient” statistics: they are first calculated per patient, and then aggregated over all patients. Other abbreviations used in this table: aut. is automatically added, man. is manually added, pct. is percentage, pds. is periods, w/ is with, w/o is without, “#” represents “number of”. An additional file shows two separate tables (one per wave) highlighting the same statistics complemented by spread measures where appropriate (see Additional file 1)
