  1. Dose to target volumes and organs at risk in Synergy Agility plans and Halcyon plans. Stated values indicate mean ± SD and statistical analysis was performed using the Wilcoxon test. The differences were considered statistically significant when p < 0.05
  2. *Not significant (NS)
  3. **Only left-sided plans were considered for the evaluation of the heart dose
