Fractionation sensitivity and equivalent doses. Commenting on the editorial by Glimelius

I have read with interest the Editorial by Glimelius [1], commenting on the paper by Brooks et al. [2] about fractionation in rectal cancer. There are some mistakes as well as some uncertainties in Table I. 1. The title of the table is ‘‘Biological equivalent doses’’. Values given in the table are BED, that is ‘‘Biologically effective dose’’, not biologically equivalent doses. Biologically equivalent doses are doses equivalent to classical fractionation given with 2 Gy per fraction. The same remark applies to Brooks paper, Table I. Readers may tend to be confused between the two terms. An example is given below for late effects, derived from Table I.
