Figure 2. Distribution and CRC risk of the genetic risk score in cases and controls.

Figure 2

The left axis scale indicates the OR for CRC according to the number of risk alleles. The group of 22 alleles was selected as reference category (OR = 1), because this is the average in the population. The right axis scale indicates the proportion of cases and controls shown in bars for each allele.
