[POBA - plain old balloon angioplasty; BMS - bare metal stent; DES - drug eluting stent; BRS - bioresorbable scaffold; + − positive/beneficial; − - negative/ no effect; ± − neutral or uncertain effect;? - lack of definitive evidence] No with direct comparison study of four techniques therefore, the table is compiled based on non-comparative data (Iqbal et al. 2014)]
