Genetic variation in 9p21 is associated with fasting insulin in women but not men - Fig 1

Fasting serum insulin by 9p21 genotype (rs10757278) in women (A) and men (B). ANCOVA was adjusted for: log-body mass index, diastolic blood pressure, log-waist circumference and plasma glucose. Fasting Insulin (pmol/L) was log-transformed, but expressed as normal mean to facilitate interpretation. Different letters, a, b and c indicate statistically significant differences in insulin concentrations between genotypes (pairwise differences) within a group which were tested only if overall ANCOVA for the group was statistically significant. p-value at the top of each group is indicative of overall differences in each group for comparing all three genotypes within the group.
