Good question Evelyn & one I've been pondering. Ioannidis recently said EBM's been 'hijacked' by vested interests (not just industry). He's referring to the 'E' in EBM. I agree. As do my colleagues bmj.com/content/357/bm… /1
For me the very word 'evidence-based' has also been hijacked to the point where I consider it meaningles in/of itself. You ask 'How do you know?'. It's simpler than you think. EBM is a SKILL. /2
