Data were expressed as mean ± standard deviation for normal distribution (age and BMI) and as median (interquartile range 25–75%) for skewed variables (WHR, TG, TC, HDL-C, and LDL-C)
BMI body mass index, WHR waist to hip ratio, TG triglyceride, TC total cholesterol, HDL-C high-density lipoprotein cholesterol, LDL-C low-density lipoprotein cholesterol, LH-NO lipid healthy and non-abdominal obese, LH-O lipid healthy and abdominal obese, LA-NO lipid abnormal and non-abdominal obese, LA-O lipid abnormal and abdominal obese, DD degenerated disc
^aMeans P < 0.05 versus LH-NO
^bMeans P < 0.05 versus LH-O
^cMeans P < 0.05 versus LA-NO
