Fig. 3From: Improvement of left ventricular ejection fraction in revascularized postmyocardial patients: indication for statistical fallacyScatter plot: relation between EF values during first (EF1) and second visit (EF2). Truncated data at 40% on the occasion of the first visit due to inclusion criteria for groups 1 and 2, approximately homogeneous during second visit.
