Mendelian randomization estimates for sex-specific associations of genetically predicted (a) serum iron (n=163,511; Bell S, et al.) and (b) hemoglobin (188,076 women/162,398 men; UK Biobank) with HbA1c (185,022 women/159,160 men; UK Biobank) and fasting glucose (73,089 women/67,506 men; MAGIC).
a. The contamination mixture method was used.
b. Estimates are expressed in standard deviation for serum iron, hemoglobin and HbA1c, and in mmol/L for fasting glucose.
