Fig. 6From: Longitudinal wall fractional shortening: an M-mode index based on mitral annular plane systolic excursion (MAPSE) that correlates and predicts left ventricular longitudinal strain (LVLS) in intensive care patientsCorrelations between LVLS and MAPSEsum, CAMMFS and LWFS for the training set. a MAPSEsum. b CAMMFS. c LWFS. The dotted line in each figure represents the line of equality, and the solid lines and shaded areas are the line of best fit ± 95%CI.
