Key Clinical Findings of the Study Include:Significant AIP Elevation: The study noted that the atherogenic index of plasma was significantly higher in obese patients compared to lean ones (0.7 vs. 0.6, p = 0.006), serving as a sensitive indicator for future coronary complications. Surpassed Cholesterol Cutoffs: Researchers observed that the Total Cholesterol (TC) to High-Density Lipoprotein Cholesterol (HDL-C) ratio reached 6.7 in obese subjects and 5.9 in lean subjects, both surpassing the recommended 3.5 clinical threshold. Inverse Glycemic Trends: The investigation found that lean patients exhibited significantly worse glycemic control, with a mean Glycated Hemoglobin (HbA1c) of 11.5% compared to 9.42% in the obese cohort. High Proatherogenic Potential: The Low-Density Lipoprotein Cholesterol (LDL-C) to High-Density Lipoprotein Cholesterol ratio was found to be 4.8 in the obese group and 4.0 in the lean group, both exceeding the sensitive predictor threshold of 2.517.
