Text: Subgroup analysis revealed similar composite end point results for true bifurcations (n = 657, simple 9. 2 % versus complex 17. 3 % ; hazard ratio 1. 90 [95 % confidence interval 1. 22 to 2. 94], P = 0. 004), wide-angled bifurcations > 60 to 70 (n = 217, simple 9. 6 % versus complex 15. 7 % ; hazard ratio 1. 67 [95 % confidence interval 0. 78 to 3. 62], P = 0. 186), large (2. 75 mm) diameter side branches (n = 281, simple 10. 4 % versus complex 20. 7 % ; hazard ratio 2. 42 [95 % confidence interval 1. 22 to 4. 80], P = 0. 011), longer length (> 5 mm) ostial side branch lesions (n = 464, simple 12. 1 % versus complex 19. 1 % ; hazard ratio 1. 71 [95 % confidence interval 1. 05 to 2. 77], P = 0. 029), or equivalent sized vessels (side branch < 0. 25 mm smaller than main vessel) (n = 108, simple 12. 0 % versus complex 15. 5 % ; hazard ratio 1. 35 [95 % confidence interval 0. 48 to 3. 70], P = 0. 57).
