TABLE 1.

The description of the distributions of average septal curvature and wall thickness ratio indexes

Wall thickness ratio
Distribution description Average septal curvature (dm−1) 4CH PLAX
Minimum −2.440 0.818 0.875
 P15 −1.163 1 1
 P25 −0.88 1.091 1
 P50 −0.362 1.167 1.125
 P75 0.041 1.333 1.286
 P85 0.335 1.429 1.413
Maximum 1.310 2.143 2.125
 Pnormal 0.035 <0.001 <0.001

Pi values denote the percentiles. P85 of WTR in either of the views is the threshold for the diagnosis of BSH. Pnormal is the P value of the test for normality. None of the distributions can be qualified as normal. 4CH, four-chamber; PLAX, parasternal long-axis.
