From: Intensity-modulated radiation therapy versus three-dimensional conformal radiotherapy in head and neck squamous cell carcinoma: long-term and mature outcomes of a prospective randomized trial

Fig. 2

Proportion of patients (error-bars represent 95% confidence intervals) with moderate to severe (≥grade 2) late xerostomia 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 consistently. Lesser number of patients at risk in both arms on long-term follow-up (at 8–10 years) reduces statistical power but, clinically meaningful difference is sustained over time
