Fig. 6. —Graphs representing mean (± SEM) number of
discrepancies in identifying abnormalities of sphenoethmoidal recess
(Fig. 5), osteomeatal unit
(Fig. 6), nasofrontal duct (Fig.
7), and ethmoid bulla (Fig.
8). X-axis represents sets of comparisons: 1, two-by-two
comparisons between pairs of reviewers at both sessions interpreting low-dose
multidetector CT (MDCT) scans; 2, two-by-two comparisons between pairs of
reviewers at both sessions interpreting standard-dose MDCT scans; 3,
intrareviewer comparisons between two interpretation sessions of low-dose MDCT
scans; 4, intrareviewer comparisons between two interpretation sessions of
standard-dose MDCT scans; 5, comparisons between interpretations of low- and
standard-dose MDCT scans for each reviewer and for both interpretation
sessions. In cases of statistically significant discrepancies, p
values from Tukey tests [24]
are given. Solid line represents significant difference involving comparisons
of low-dose and standard-dose scans among reviewers. Dashed line represents
significant difference involving another comparison. Vertical bars extending
on either side of mean point represent range.
