Dose-response analyses of dietary intakes of total iron and heme iron in relation to risk of type 2 diabetes mellitus (T2DM) in the included studies. The risk estimate of dietary total iron intake for T2DM risk in the Iowa Women's Health Study (Lee et al [24])) was not directly reported, and thus this was pooled from the results of dietary non-heme iron intake and heme iron intake in this study.
