CD4 and atrial fibrillation: In stark contrast, plasma VL was higher in AF-positive dams compared to AF-negative dams in the CD4-depleted groups (punadj = 0.004, pFDR = 0.044, Table 1 and Fig 7), driving a significant difference in the maternal plasma VLs in the combined group including both all treatment groups (punadj = 0.0013, pFDR = 0.0014, Table 1).
