APOB and arthritic joint disease: Furthermore, univariate analysis showed that age (p = 0.001), age at disease onset (p = 0.003), arthritis (p = 0.014), weight (p = 0.000), BMI (p = 0.000), hypertension (p = 0.002), and the rs11960458 SNP in AnxA6 (p = 0.014) were significantly associated with ApoB levels.
