Figure 3 The sensitivity and specificity curves identified different optimal thresholds of minimum stent area (MSA) to predict adequate follow-up minimum lumen area (MLA): 5.0 mm² for sirolimus-eluting stents (SES) and 6.5 mm² for bare metal stents (BMS). Sirolimus-eluting stents may achieve better longer-term outcome with an "optimized" lower MSA threshold. Triangles = sensitivity; circles = specificity.
