Figure 3 Representative linear fit curves for injury-dependent neointimal thickness in the four studied groups. (A) shows regression lines for handled + not-rinsed and handled + rinsed stents, which showed significantly different slopes (allowing any intercept: p = 0.004; forcing a fixed intercept: p = 0.003). (B) injury-dependent neointimal thickness regression lines for untouched + not-rinsed and untouched + rinsed stents, which also showed statistically significant differences in slopes (allowing any intercept: p = 0.037; forcing a fixed intercept: p = 0.011). Measurements were made on three cross-sections from each stent.
