Proportion of patients (error-bars represent 95% confidence intervals) with moderate to severe (≥grade 2) subcutaneous fibrosis at specified time-points in three-dimensional conformal radiotherapy (3D-CRT) and intensity modulated radiation therapy (IMRT) arms. Note the statistically significant p-values favouring IMRT in the medium-term (1 and 3 years). Lesser number of patients at risk in both arms on long-term follow-up (between 5 and 10 years) reduces statistical power, but, clinically meaningful difference persists with time
