WebObjective: To investigate the influence of the pancreas lipase inhibitor orlistat (OLS) on calcium metabolism, bone turnover, bone mass, bone density and body composition when given for obesity as adjuvant to an energy- and fat-restricted diet. Design: Randomized … WebOLS induces a relative increase in bone turnover in favour of resorption, possibly due to malabsorption of vitamin D and/or calcium. However, no changes in bone mass or density are seen after 1 y of OLS treatment apart from those explained by the weight loss itself. Thus 1 y of OLS treatment seems safe from a 'bone preserving' point of view.

Furthermore, multi-collinearity and Post-treatment bias causes different … WebThe Assumption of Linearity (OLS Assumption 1) – If you fit a linear model to a data that is non-linearly related, the model will be incorrect and hence unreliable. When you use the model for extrapolation, you are likely to get erroneous results. Hence, you should always plot a graph of observed predicted values.
