On the other hand, we found that although Gemmiger was positively associated with six lipid indices in the AF group and negatively associated with two lipid indices in the AM group, in the MA group, which was composed of the AF and AM groups, only sdLDL-C and ApoE were associated with Gemmiger. This result was caused by the fact that the MA data were mixed from both AF and AM groups, which obscured the differences related to gender factors. Here, APOE is linked to atrial fibrillation.
