After adjusting for age, gender, body mass index, glucose, albumin, creatinine, SGOT, CRP, cholesterol, triglycerides, systolic blood pressure and diastolic blood pressure, it could be observed that diabetes mellitus, death, DSS and DHF and increased GPT levels significantly lowered the platelet counts during the first day of hospitalization for dengue fever with regression β of −13.981 (95% confidence interval (CI) −27.587, −0.374), −26.847 (95% CI −37.562, −16.132), and 0.054 (95% CI 0.015, 0.094), respectively (Table 3). This evidence concerns the gene GPT and diabetes mellitus.
