Multivariate linear regression analysis of pre-operative factors with excess BMI loss at both six months and one year post-operatively. Multivariate regression for %EBMIL, six months: r2 = .36, n = 547, F = 76.2, P < .001; Multivariate regression for %EBMIL, one year: r2 = .33, n = 547, F = 67.4, P = <.001.
