Figure 5 : Positive predictive value for CRC according to age range and risk score.

From: Risk Model for Colorectal Cancer in Spanish Population Using Environmental and Genetic Factors: Results from the MCC-Spain study

Figure 5

Colour lines indicate the positive predictive value (PPV) for CRC for each age range. Estimates are derived from sensitivity and specificity of the risk model (Table 4) for each risk score applied to the cumulative risk of developing CRC in the age range, using Bayes’ theorem.
