approached significanceP = 0.05
Although there was weak-to-moderate association ( r = 0.29 to −0.48) on pooled analysis for TAPSE, S′, RV-GPLS and RV-FWPLS, once within-subject association was accounted for by ANCOVA, only RV-FWPLS approached significance ( P = 0.05) with weak association ( r = 0.31).
