Excerpt of an example de-identified published database from 1914, “Some Experiments in Standardization of Dosage” [33]. Although precision is limited since this table pre-dates the definition of the rad by 4 decades [35] and was long before any of the modern grading systems [4], nevertheless the sharing of fractionation, multiple parameters of dose, and outcome per patient as still recommended by HyTEC and QUANTEC [10,11,12, 32] is truly remarkable, since this dataset of 197 cases is from more than 100 years ago
