Developing a scoring method for evaluating dietary methodology in reviews of epidemiologic studies.

We examined the quality of dietary assessment used by studies of prostate cancer and dietary fat in an attempt to explain the heterogeneity of their relative risk (RR) estimates.

We scored studies based on several objective measures of quality dietary assessment.
