SPP1 and polyp: As shown in Figure 3a–d, significant positive correlation between serum levels of TGs and polyp numbers was observed in Min/OPN(+/+) (r = 0.68 by the Pearson correlation coefficient test, p = 0.00019; rs = 0.74 by Spearman’s rank correlation coefficient test, p = 0.00031) Min/OPN(+/−) (r = 0.72, p = 3.1 × 10−10; rs = 0.74, p = 3.4 × 10−8), Min/OPN(−/−), (r = 0.64, p = 3.0 × 10−5; rs = 0.71, p = 2.5 × 10−5), and all three genotypes (r = 0.66, p = 9.5 × 10−16; rs = 0.71, p = 2.7 × 10−15).
