Similarly, combined factor 2 (a combination of clinical factors and exercise time) = (-1.448) + (-0.254) × age + 1.294 × visceral obesity + 0.512 × hypertension + 1.222 × hypertriglyceridemia + 0.610 × low HDL-C + 0.958 × ALT + (-0.220) × exercise time; combined factor 3 (a combination of clinical factors, exercise time and SNP genetic variant) = (-1.519) + (-0.334) × age + 1.296 × visceral obesity + 0.503 × hypertension + 1.240 × hypertriglyceridemia + 0.631 × low HDL-C + 1.004 × ALT + (-0.225) × exercise time + (-0.264) × rs2228570. The gene discussed is GPT; the disease is hypertriglyceridemia.
