The researchers believe that this weak association is likely a “false-positive,” and there is no “strong evidence to support smoking as a risk factor.” In this model, the disease manifests when the “threshold of liability,” a fixed point on the scale of overall risk, has been exceeded (Table 1).3-5. 2003 Jul-Aug. 22(4):217-28. 18(5):745-54.

The liability model assumes an underlying normally distributed susceptibility for the disease within a population, where an individual’s total risk reflects the combination of genetic and nongenetic factors acting to alter an individual’s chance of developing a disease. By contrast, pedigree studies can achieve greater numbers by assessing differences in phenotype presentation across parent-offspring trios to determine narrow-sense heritability, which indicates the extent to which an exhibited phenotype will be transmitted from parent to offspring.
