Regression coefficients indicate the marginal effect of each attribute (or attribute level) on the utility for genomic sequencing. Positive (or negative) mean estimates indicate, on average, a positive (or negative) effect on utility. Standard deviation estimates describe the heterogeneity of preferences among study participants.
