13 8 Often thinking about the recipient/the family of the recipient Anonymous contact with recipient (yes) 0.04 2.67 0.80–8.91
14 8 More often thinking about own family since reception of the news Contact (letter) 0.05 1.85 0.82–4.16

  1. All combinations of answers and factors with p values < 0.05 are displayed. Due to multiple testing, only p values < 0.0005 are considered as significant and marked with an asterisk in the table. Examples: Donors who have been contacted by phone significantly more often prefer phone communication than other donors (#2). Female donors more often state to often think about the recipient or his family than male donors but the difference is not regarded as significant (#12). P = Pilot.
