Decisional conflict score at three months. Values are means (SDs) unless stated otherwise

	Intervention group	Control group	Mean difference (95% CI)
Uncertainty	2.4 (0.8)	2.7 (0.8)	−0.3 (−0.6 to 0.0)
Factors contributing to uncertainty	2.3 (0.5)	2.7 (0.6)	−0.4 (−0.7 to −0.2)**
Perceived effective decision making	2.0 (0.4)	2.2 (0.6)	−0.2 (−0.4 to −0.002)*
Total decisional conflict score	2.3 (0.4)	2.6 (0.5)	−0.3 (−0.5 to −0.1)**

The decisional conflict scale contains three subscales that elicit uncertainty about choosing between alternatives, awareness of modifiable factors contributing to the uncertainty, and perceived effectiveness of decision making process. Higher scores indicate increased uncertainty in each subscale. Subscales can be combined to give a total decisional conflict score. Subjects with strong intentions to accept or decline a health intervention tend to lower scores and those who remain uncertain tend to higher scores.^{12 *}P<0.05. ^**P<0.01.
