Graphs show the proportion of patients with positive findings () and of patients with follow-up recommendations () over the total number of patients per age group. (a) Overall, the proportion of patients with positive findings and recommendations progressively increased with age, and a similar pattern was noted in (b) men and (c) women. Proportions of recommendations were higher for women than for men, although the difference was not significant (P = .19).

Graphs illustrate the ratio of findings per patient () and the ratio of recommendations per patient () and per finding () over the total number of patients per age group. (a) Overall, the number of findings and recommendations per patient increased as the age increased; the number of recommendations per finding was similar for all age groups, except for a nonsignificant increment in middle-aged patients (40–49 and 50–59 years old) (P = .09). Similar patterns were seen for (b) men and (c) women. Women had a higher number of recommendations per finding (P = .001) and per patient (P = .14) than did men in all age groups.

The distribution was similar for each age group; abdominal findings were the most common findings, and thoracic findings were the least common findings according to age group.

Overall, CT was the most frequent recommendation, which was indicated in 50% (144 of 289) of recommendations for abdominal findings. CECT = contrast-enhanced CT, WBCTS = whole-body CT screening.
