A) Relation between average circumferential stress σ_θ,AVG and opening angle (OA) from experimental measurements of the swine left anterior descending artery (Ref. 15). Data can be fitted with a linear equation as: σ_θ,AVG = 0.115OA + 124.5, R² = 0.32, p-value <0.0001; B) Relation between stress distribution factor $(\frac{{\sigma }_{\theta ,e}}{{\sigma }_{\theta ,i}})$ and opening angle (OA) based on experimental measurements of swine left anterior descending artery (Ref. 15). Data can be fitted with a linear equation as: $\frac{{\sigma }_{\theta ,e}}{{\sigma }_{\theta ,i}}=0.0278\mathit{\text{OA}}-2.56$, R² = 0.84, p-value <0.000001.
