True; for many questions in health(care) there is never a definitive answer.

I guess my opinions just reflect my conviction of the value of (1) old-fashioned clinical skills - I think that a thorough history and physical examination is likely to yield much more meaningful clinical information than a whole load of "objective" laboratory or physiological scores without any context in which to interpret the results and (2) critical appraisal of the literature / evidence-based medicine.

You'd be hard pressed to find a [half decent] doctor who disagrees with either of those principles
