The effects in the younger subgroup (<70 years) were slightly stronger than those in the older subgroup ( Supplemental Table 3 ); the age by PC2 CMTN interaction term was marginally significant ( P = 0.05 in the full model).
Although similar findings were observed for MYLIP, the association between its protein expression and mRNA expression was marginally significant ( r = 0.39; P = 0.058), and the associations between protein levels and cellular cholesterol did not reach statistical significance ( P = 0.22).
