In the presence of AS, dilated cohort had lower WSS mag than non-dilated cohort but did not reach statistical significance ( p = 0.31).

a positive trendno p-value reported

However, a positive trend was observed for all WSS metrics in the BAV cohort while no trend was observed for any of the WSS metrics in the TAV cohort.

a negative trendno p-value reported

Interestingly, by accounting for the presence of AS, a negative trend was observed between WSS mag and aortic diameter ( Figures 5 , 6 ) though it did not reach statistical significance, resulting in an apparent paradox compared to when AS was not accounted for as an additional variable ( Figures 3A , 4 ).
