Group	TG (mmol/L)	TC (mmol/L)	HDL (mmol/L)	LDL (mmol/L)	MDA (nmol/L)
AD	1.29±0.42	3.59±0.82	0.97±0.49	2.85±0.76	1.43±0.41
Controls	0.83±1.17	2.56±0.88	1.35±0.59	1.93±0.48	0.86±0.14
t-value	1.589	1.884	2.241	3.589	2.547
P-value	0.045	0.040	0.024	0.016	0.036

Notes: All data presented as mean ± SD (n=147 for AD patients and n=160 for healthy controls). Student’s t-test was used to evaluate statistically significant differences (P<0.05).

Abbreviations: TG, triglyceride; TC, total cholesterol; HDL, high-density lipoprotein; LDL, low-density lipoprotein; MDA, malondialdehyde; AD, Alzheimer’s disease; SD, standard deviation.
