> You lost me here - because the science based one is just stating unproven statements to come to some conclusion. If you were to expand on why those two sentences are "proven" you'd likely come to evidence based reasons.
I'm not sure I'm exactly understanding what you're getting at. If you expand on those statements to find direct evidence of MACE (of which there is plenty) then it is an evidence based medicine decision not a science based one.
Please disregard the specific intervention being discussed, it's just an example of the different thought processes and decision making between SBM and EBM. In real life there is plenty of science and evidence behind statins but I'm not intending on addressing reality or why this specific intervention is in use today.
Note the "medicine" part in these refers to the clinical practice of medicine. Maybe this is clearer:
The science based medicine approach (as traditionally defined) only considers the mechanisms and "indirect evidence" when making the clinical recommendation (i.e. statins are proven to lower cholesterol which are strongly correlated with MACE. Cholesterol reduction has also been proven to reduce plaque formation and artery stenosis, therefore we expect MACE will be reduced through statin use and are deciding to administer the intervention).
In this thought process we have not directly measured the outcome of interest (MACE) but we are giving an intervention because it makes sense/through chain of thought, or in other words we are intervening to optimize a variable (serum cholesterol levels) because we have reason to believe this variable reduces MACE based on the mechanism (which may have components proven by evidence like reduction in plaque formation but the primary outcome measure we are discussing, MACE, has not been measured).
In the evidence based medicine approach we are deciding to provide an intervention based on direct measurements of the outcome of interest in a specific population (i.e. less MACE was directly proven) and the decision making process is entirely independent of the mechanism or nature of the intervention (i.e. we are not considering plaque formation and cholesterol levels, simply that statins reduce MACE).
