Results
Fig. 1 provides an overview of the dose metrics and patient parameters for all 880 PCI procedures.
The table shows the ranges of the relevant parameters for male and female patients for PCI,
PCI MV,
and PCI CTO.
Fig. 2 shows the local dose reference levels (percentiles Q2 & Q3)) for Peak Skin Dose (mGy),
RPAK(mGy) and DAP (Gycm2) for all PCI studies in each of the three categories: PCI,
PCI MV,
PCI CTO.
The data includes the mean values of age,
weight,
height and BMI for patients in each category. Where available the dose metrics are compared with published values

Fig. 3 and Fig. 4 show the breakdown of the dose metrics for female and male patients respectively from the data in Fig 2.
Fig. 5 Shows the correlation between dose metrics and patient parameters (age,
height,
and weight) for each type of PCI study.
The data for males and females are separated to facilitate comparisons
Fig. 5: Pearson correlation coefficients with colour coding showing the relative strength of a linear association between the patient parameters in the columns and the dose metrics in the rows. The top three segments are correlations for female patients in the three different PCI categories, the bottom three segments relate to male patients.
