^*Satisfaction with cosmetic outcomes was measured by an interval scale derived the mean of 6 items, as described more fully in the methods section. Mean (SD) of the scale was 3.33 (1.02), with a minimum of 1 and maximum of 5. Cronbach's alpha was 0.90.

^**measured in all patients but 205 patients were not included because of missing values either in dependent or independent variables

^***BMI centered about 30, such that every one-unit increase in BMI results in an average of a 0.02 unit decrease in satisfaction, and each one-unit decrease BMI below 20 results in a 0.02 unit increase in satisfaction

^****Age centered about 60, such that every one-year increase in age results in an average of a 0.003 unit increase in satisfaction, and each one year decrease in age below 60 results in a 0.003 unit decrease in satisfaction
