Table 3 Differences in decision-making, decisional conflict, knowledge and DA use between women who received information only or information plus VCE (subdivided by referral to the VCE, and use of the VCE) (N = 197)

From: Values clarification in a decision aid about fertility preservation: does it add to information provision?

  Information only VCE- (N = 65) Information plus VCE (VCE+) (N = 132)     
  A No referral to VCE (n = 66) With referral to VCE (n = 66)    Primary analysis (A vs B vs E) Secondary analysis (H vs I)
  Total (no referral) (N = 66) VCE not used (VCE + -) (n = 31) VCE used (VCE++) (n = 35) Total (with referral) N = 66 VCE not used (VCE + -) (n = 17) VCE used (VCE++) (n = 49) Total VCE not used (C + F)(n = 48) Total VCE used (D + G)(n = 84) F- value F- value Post hoc analysis
