ALT: Alanine transaminase; AST: Aspartate aminotransferase; BMI: Body mass index; FBS: Fasting blood sugar; FE: Fisher’s exact test; HDL: High-density lipoprotein; HOMA-IR: Homeostasis Model Assessment insulin resistance; IQR: Interquartile range (25^th – 75^th percentiles); LDL: Low-density lipoprotein; Max: Maximum; Min: Minimum; NA: Non-applicable; SD: Standard deviation; SEPP1: Selenoprotien P1; VAI: Visceral adiposity index; W/H Ratio: Waist/height ratio; χ²: Pearson’s Chi-square test for independence of observations; Z: Mann-Whitney test; r_s < 0.3: Weak correlation; 0.3-0.7: Moderate; > 0.7: Strong correlation (regardless of the + /- signs); -ve sign: Inverse correlation (one variable increases while the other variable decreases); + ve sign: Direct correlation (both variables decrease or increase together).
