The minimum detectable OR for each circulating lipid trait was at 80% power of periodontitis and α=5%, the expected OR were ≤0.82 or ≥1.21 for apo A1, ≤0.76 or ≥1.29 for apo B, ≤0.80 or ≥1.23 for HDL-C, ≤0.78 or ≥1.26 for LDL-C, and ≤0.69 or ≥1.40 for TG (Supplementary Table 3). Here, APOB is linked to periodontitis.
