Table 1.
Information on baseline risks.
Table 2.
Ten examples of commonly or basically false and misleading information in CRC screening leaflets and booklets.
Table 3.
Reported benefits of CRC screening in general and for colonoscopy and the FOBT in particular in the identified leaflets (n = 28) and booklets (n = 13).
Table 4.
Reported harms of screening colonoscopy due to colonoscopy preparation, sedation and/or the procedure itself in the identified leaflets (n = 28) and booklets (n = 13).
Table 5.
Reported accuracy of CRC screening tests in leaflets (n = 28) and booklets (n = 13).
Figure 1.
Presentation of numerical data (28 leaflets, 13 booklets).
Results from the criteria characterising the quality of numerical data: 1. Natural frequencies instead of percentages are used. 2. Same denominators are used.
Figure 2.
Aggregated results for reported benefits and harms, stratified by leaflets and booklets.
The figure indicates whether a leaflet contains any information on the benefits of CRC screening a) in general or specifically for b) colonoscopy or c) the FOBT, and whether it contains any information on the d) general and e) specific harms of colonoscopy. To be rated positive for harms, it was not sufficient if the only information about possible harms referred to pain, stating incorrectly that there is no pain involved.
