Design outcomes
Primary
| Measure | Time frame |
|---|---|
| For each X-ray examination, two specific values are calculated as target values for each age cohort: 1. The so-called “typical value”: This dose value corresponds to the “average” dose-area product value in cGy·cm² and is defined as the median value of the pooled analysis or (if the cohort under consideration is sufficiently large) as the mean of all median values for the individual devices. 2. The “diagnostic reference value”: This value is to be defined as an upper dose value analogous to the diagnostic reference level. It is determined either by the 75th percentile of the pooled analysis or (if the size of the cohort under consideration is sufficient) as the mean of all 75th percentiles of the individual devices. | — |
Secondary
| Measure | Time frame |
|---|---|
| To provide a comprehensive description of the dose distribution and to identify outliers, the arithmetic mean and the standard deviation, the minimum and maximum, as well as the 25th percentile (interquartile range - IQR) and the number of cases per device and age cohort are also collected and analysed. | — |
