They analyzed the results of 305 randomized controlled trials involving 339,274 individuals and found no statistically detectable differences between exercise and drug interventions for secondary prevention of heart disease and prevention of diabetes.I plan to review the paper today but remember that randomization protects against many possible sources of bias. It doesn't mean that these recommendations apply to all patients at all times, nor does it address the possibility of additive effects. If you are thinking of changing your activity level it is prudent to discuss potential risks with your health care provider in advance.
But it makes it clear that we under-utilize a really remarkable treatment.
