  1. No association (0): 0%–33% of the papers reported a statistically significant difference between LPA and outcomes, Indeterminate (?): 34–59% of the papers indicated a statistically significant difference, and favorable association (+)/ unfavorable association (−): 60%–100% of the papers showed a statistically significant favorable / unfavorable difference, respectively. When more than four studies supported an association or no association, it was coded as “00”, “++”, or “−−”. “??” indicates inconsistent findings
  2. BMI Body mass index, BP Blood pressure, DBP Diastolic blood pressure, SBP Systolic blood pressure, WC Waist circumference, HDL-C High density lipoprotein cholesterol, LDL-C Low density lipoprotein cholesterol, HOMA Homeostasis model assessment, CRP C-reactive protein
  3. N indicates the number of studies included in the review. n indicates the number of studies showing a favorable association
