SDM = shared decision-making. Boldface values indicate characteristic is significantly related to the outcome variable at P ≤ .05.

^aPercentage correct responses using ordinary least square regression.

^b1 = scores of 3 and 4 and 0 = scores from 0 to 2 using logistic regression.

^c1 = some decisional conflict and 0 = no decisional conflict using logistic regression.
