Demographic data including age and gender were recorded, and lipid profiles (triglycerides, high-density lipoprotein, and low-density lipoprotein) were assessed using standard clinical measurements. Statistical analyses determined frequency distributions of age groups, gender proportions, and lipid profile categories.
