Should all manuscripts be statistically reviewed?

All medical scientific publications do not present evidence based research. Many, if not all, hypothesis presentations, non-systematic reviews, and case reports are authority based rather than evidence based. Also such publications may have a role to play for the progress of science. It should, however, always be made clear to the reader whether the author's ambition has been to present a personal opinion or an objective and reproducible research finding. From an editorial point of view, it may be difficult to distinguish between these two types of manuscripts; the author's ambition is seldom declared and statistical inference is often misused. Personal opinions should, of course, not be statistically reviewed because statistical reviewing can make a good expert opinon appear to be bad and a poor one to appear to be good.
