APOM and Alzheimer disease: Besides, each of the ApoM-derived indicators that include the ratios of ApoM/TC [12.29 (9.49–15.52) vs. 19.17(13.55–23.34), p < 0.0001], ApoM/TG [30.26 (24.62–42.24) vs. 55.20 (41.61–77.64), p < 0.0001], ApoM/HDL-C (40.43 ± 14.46 vs. 61.85 ± 24.97, p < 0.0001), and ApoM/LDL-C [21.50 (16.52–32.19) vs. 30.48 (24.24–42.01), p < 0.0001] was significantly higher in AD group than that in CN group (Table 1 and Figure 1).
