Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI)
時間枠:8 weeks
|
Effect of P-OM3 dose on the homeostatic model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI). HOMA-IR calculates an index of insulin resistance and is calculated as follows: HOMA-IR = (glucose mg/dL * insulin mU/L) / 405. QUICKI is calculated as follows: QUICKI = 1 / (log(fasting insulin µU/mL) + log(fasting glucose mg/dL)). |
