CT computed tomography, HRA high resolution axial algorithm, HROA high resolution oblique algorithm, SAA standard axial algorithm, SOA standard oblique algorithm. Comparison of HRA, HRO, and SAA with SOA: the U values of a2541.50, b14478.00, c18292.50, d2870.00, e16537.00, and f19508.50, respectively. Comparison of HRA and SAA: the U values of g25832.00 and h25141.50, respectively. Comparison of HRA and HRO: the U values of i20910.00 and j21283.00, respectively. The p value was < 0.001 for all statistical analyses
- M (P25, P75) represents median (25th percentile, 75th percentile)
- H in the stub represents the statistic value obtained from formula Kruskal-Wallis test. It is equivalent to the chi square value obtained by chi square test
