To the Editor: Dr Mundinger and colleagues1 state that their results support the "hypothesis"
that there is no difference in patient outcomes between nurse practitioner
and physician care. However, this is really the null hypothesis, and their
study simply failed to find a difference. This seemingly semantic argument
actually has an important basis—that of the difference between statistical
and clinical significance. Current research methods may provide only a blunt
tool with regard to dissecting what must predictably be small but nonetheless
important shades of gray in primary care outcomes.
