Groups and cohorts

What researchers measure

Primary outcomes

  1. Mean BMI Change

    Mean change in BMI for valid subjects

    Time frame: 3 years follow-up

  2. Mean Excess Weight Change

    Mean excess weight change in valid subjects. Excess weight is calculated as body weight minus ideal body weight, where ideal body weight is determined by the method of Lorentz (Ein neuer Konstitionsinde. Klin Wochenschr 1929; 8:348-51).

    Time frame: 3 years follow up
