In the fibrate user group (n = 6), the LPL levels were significantly lower (43.4 vs. 62.5 ng/mL, p = 0.038), while the HOMA-IR values (2.3 vs. 1.4, p = 0.042), diabetes prevalence (33.3% vs. 4.8%, p = 0.018), and TG levels (178.5 vs. 105.0 mg/dL, p = 0.016) were significantly higher. This evidence concerns the gene LPL and diabetes mellitus.
