There is this infamous DANCAVAS study [1] in which they ran cardiovascular screening on older population and found absolutely no benefit in doing so. Note that while the linked study claims there was a benefit to screening (reduced mortality in men aged 65-69), the apparent effect was caused by improper statistics (primary endpoint did not show benefit, only subgroup analysis, which however lacked statistical power to be reliable). And indeed, their follow up study showed that there was no benefit in the subgroup. [2]
Many a dollar is wasted every year on trying to prove population-wide screening prevents mortality or increases patients’ quality of life and every time we don’t cheat with statistics we get the same answer - population-wide screening isn’t effective.
