a nonsignificant trendP = 0.07
In fact, the remodeling of the ATA during pregnancy even leads to a nonsignificant trend of decreasing circumferential and axial wall stresses ( P = 0.07 for the comparison of the circumferential stress, and P = 0.09 for the comparison of the axial stress), as illustrated in Figs. 6(b) and 6(e) .
