From: Evidence at a glance: error matrix approach for overviewing available evidence
Matrix step I, ordering of evidence according to systematic error (in levels of evidence) and random error (measured by standard error) considering all-cause mortality in antiarrhythmics for maintaining sinus rhythm after cardioversion of atrial fibrillation (example 2). Compare this figure with Figure 3: the studies in this figure are located on the right side of the figure (all SE >0.40), in contrast with Figure 3 where the studies are concentrated on the upper left side of the figure (six studies with SE < 0.40).>
