The proportion of evidence-based health care gives rise to controversy. Estimates range from 4%-20%. Studies trying to ascertain the proportion of evidence-based healthcare show wide variations in the results depending on design, setting, subject, main outcome measures, methodology and definition of evidence from 11-82%. The results should not be generalized to community health care and should not be misused in public discussions.
