Figure 2From: Right atrial to left atrial area ratio on early echocardiography predicts long-term survival after acute pulmonary embolism Kaplan-Meier survival analysis for the Derivation Cohort. a: Kaplan-Meier survival curve of the Derivation Cohort: post-discharge following acute PE utilising a cut-off of RA/LA area ratio of 1.0 on Day 1 post PE adjusted for other variables in the multivariate model. p = 0.04. b: Kaplan-Meier survival curve of the Validation Cohort: post-discharge following acute PE utilising a cut-off of RA/LA area ratio of 1.0 on Day 1 post PE adjusted for other variables in the multivariate model. p = 0.04.Back to article page
