CRP and Insulin resistance: Owing to this consistency across clinical trial studies, the main objective of this systematic review and meta-analysis was to summarize the effects of green tea supplementation on cardiovascular risk factors including glycemic control markers (fasting blood sugar (FBS), hemoglobin A1C (HbA1c), homeostatic model assessment for insulin resistance (HOMA-IR), fasting insulin), blood pressure (systolic blood pressure [SBP] and diastolic blood pressure [DBP]) lipid profile (TG, TC, LDL, HDL) and C-reactive protein (CRP).
