Correlations among equipment variables and patient features: per each couple of variables, scatter plot and spearman correlation value have been reported. Lower matrix: scatter plot; Upper matrix: correlation with Spearman Correlation Coefficient.The Spearman correlation coefficient, rs, can take values from + 1 to − 1. A rs of + 1 indicates a perfect association of ranks, a rs of zero indicates no association between ranks and a rs of − 1 indicates a perfect negative association of ranks. The closer rs is to zero, the weaker the association between the ranks. PD percent density (%), BMI; BPT body part thickness (mm), KVP kVp; ED entrance dose (mGy). In small font (red in color version) not significant correlations (p > 0.05)
