LPA and diabetes mellitus: The results of univariable Cox proportional hazard analysis also showed that high Lp(a) was associated with all-cause death (HR 1.449, 95% CI 1.130–6.858, P = 0.033) and rehospitalization (HR 3.163, 95% CI 1.017–6.328, P = 0.045) in patients with diabetes; high Lp(a) was associated with rehospitalization in men (HR 1.103, 95% CI 1.025–4.207, P = 0.043) (Table 3).
