This, the primary outcome measure, provided the best linkage results, peaking with a LOD of 3.3 on chromosome 6 at marker SE30 (between D6S344 and D6S470), when using the younger dataset. A less substantial peak (LOD = 2.3) was found in the same region at marker ATA109H09, using the older dataset. In both datasets, this peak declined as lighter drinkers were progressively dropped (see Figure 2).
