In another study involving 3929 patients of which 21% were T2DM patients, a higher all-cause (men - HR: 1.75; 95% CI: 1.32-2.32; women - HR: 1.66; 95% CI: 1.08-2.56) and cardiovascular mortality (men - HR: 2.16; 95% CI: 1.27-3.67; women - HR: 2.84; 95% CI: 1.38-5.89) was observed with higher PRL concentrations; however, this result did not adjust for BMI [18]. Here, PRL is linked to type 2 diabetes mellitus.
