The authors were made aware that the wrong a/b was used for EQD2 calculation. This may lead to erroneous dose calculation and dose sum assessment. The error on page 4 of the article PDF reads: “use of a regime delivering a biologically equivalent dose above 36 Gy in 18 fractions to the target (corresponding to a EQD2Gy of 36 Gy; Table 4; recommendation 8; using an a/b value of 3 Gy).” Correctly, it should read: “using an a/b value of 10 Gy).” The error has been corrected in the online version.
