  1. In multivariate model 1, no left atrial longitudinal strain was included as a covariate. In multivariate model 2, reservoir εs was included as a covariate. In multivariate model 3, conduit εe was included as a covariate. In multivariate model 4, all parameters of left atrial longitudinal strain were included as covariates
