a
50 keV had significantly worse ratings than 60, 70, 80, and Iodine (p<.0001)
b
60 k eV had significantly worse ratings than 70 keV (p<.0001)
c
70 keV had significantly better ratings than 80 keV and Iodine (p=0.0009 and 0.0012, respectively)
P-values incorporate the Bonferroni adjustment for multiple comparisons.
