Informed subscore	100	38.2±38.0	31.0±31.4	−8.0 (−14.8 to −1.2)	0.02
Values clarity subscore	100	27.9±36.1	18.4±29.0	−10.0 (−17.3 to −2.7)	0.008
Support subscore	100	13.4±20.2	11.6±19.5	−2.0 (−5.7 to 1.7)	0.29

Total score: 0 (no decisional conflict) to 100 (extremely high decisional conflict); subscales: 0 (‘good’, eg, ‘extremely certain’) to 100 (’bad’, eg, ’extremely uncertain’).
