Such randomised controlled trials find out how a drug works overall, but there will be some people for whom the drug works well and others for whom it didn’t work at all. N-of-1 trials address this by focusing on just one patient. When he told his consultant why he’d stopped taking statins, he was put on an N-of-1 trial. An analysis of N-of-1 trials published in The BMJ in February led to two-thirds of participants saying they’d take statins again. Currently N-of-1 trials are only being used in research.
