Crap study by the looks of it. If you wanted to design a study likely to find no problems, that would be a possible one. Only 60 patients, all previous users, and the least troublesome statin used. Design excludes culmulative side effects that take months or years to become noticeable, exercise-induced effects and side effects of the non-medicinal pill ingredients.
Some key info is subscription only, such as dose, protocol (you are meant to ramp up statin dose initially) and the profile of the subjects (were they on statins for any heritidary reasons, age reasons or lifestyle?).
This study is probably going to cause sufferers of statin myopathy and many other medication problems a lot of mental health damage over the next few months as it gets propagated by a few people who should know better and many who don't. The study authors and the New England Journal of Medicine should be ashamed.
And I feel
@lazybloke's son is not being allowed to make an informed decision if the patient information leaflet (PIL) is being withheld. Whether that is a problem probably depends how old they are and whether they are officially dependent. I think I always had my PILs from age 10ish but I only reported side effects on my long term meds at age 32 and even that took a doctor to point out.
