Correction to “Early generation dynamic and static proton arc treatment planning algorithms assessment in oropharyngeal cancer patients”

An outdated figure was used in the published version of the manuscript in results section "3.3 Inter-fraction robustness, figure 4".The old image that made it to the published version excluded the data for a 7th planning technique "30B 420L ELF + 2RS", which was added during the revision process.Below you can find the correct figure [4] with the accepted data included.F I G U R E 4 Robust target coverage metrics for IMPT and PAT plans generated using the ELF, ELSA and SPArc algorithms for six oropharyngeal cancer patients.Robust target coverage was evaluated on 42 weekly repeated CTs and accumulated over the repeat CTs for each patient.Dashed line = Cumulative coverage threshold, Box = interquartile range (25th-75th percentile), solid line = median, x = mean, whiskers = range, dots = outliers.We apologize for this error.
