Efficacy and cost of high-frequency IGRT in elderly stage III non-small-cell lung cancer patients
Fig 2
Cumulative incidence of acute toxicities calculated via claims for hfIGRT (dashed line) and other (solid line).
No statistically significant difference was observed for any of the endpoints except esophageal toxicity. Although hfIGRT was associated with increased esophageal toxicity among all patients, this association did not withstand an analysis using propensity score matching. Abbreviations: hfIGRT = high frequency image guided radiation therapy.
