On randomized controlled trials and lifestyle interventions.
Randomized controlled trials (RCT) are viewed as the ultimate method for evaluation. The author claims that RCT do not enable full evaluation of lifestyle interventions in particular. Lifestyle interventions usually affect several diseases not measured by RCTs and the people who have undergone these interventions also have an impact on the lifestyle in their immediate environment. These potential biases indicate that RCTs underestimate the value of lifestyle interventions.
