Deviations from reference doses and Z-scores. (a-f) Boxplot of the deviation (in Gy) of the dose estimates compared to reference doses (orange line) in terms of air kerma (a & d), absorbed dose to blood (b & e) or matching the dose definition of the applied calibration curve (c & f). Manually scored results are shown in blue (a-c) and semi-automatically scored results in red (d-f). The symbols indicate whether the source used for the establishment of the calibration curves used for dose estimation was calibrated in terms of air kerma (=) or dose to water (< ). (g-i) Z-Scores relative to reference doses in terms of air kerma (g) or dose to blood (h) or matching the dose definition of the applied calibration curve (i). The orange lines indicate the thresholds for questionable results (± 1.96). The symbols indicate the blind samples △ ref. dose 1; ref. dose 2; ref. dose 3).
