PURPOSE: Cardiorespiratory fitness is suggested to be an important marker of cardiovascular risk, but is rarely evaluated in healthcare settings. In the present study directly measured peak oxygen uptake data (VO2peak) from a diverse population of 4637 healthy participants were used to develop and cross-validate a new non-exercise regression model of cardiorespiratory fitness for men and women....

Use of disease simulation models has led to scrutiny of model methods and demand for evidence that models credibly simulate health outcomes. We sought to describe recent obstructive lung disease simulation models and their validation. Medline and EMBASE were used to identify obstructive lung disease simulation models published from January 2000 to June 2006. Publications were reviewed to assess...
