Results are displayed as frequencies (percentages), metric data as mean ± SD if normally distributed or median with interquartile range (25–75th percentile) if not normally distributed. p < 0.05 is considered statistically significant; PET/CT  positron emission tomography/computed tomography, SUV  standardized uptake value, IQR Interquartile range. Significant values are in bold.
