Table 2 provides a description of the sample used in the statistical models. Nine percent experienced two or more traumatic events in their lifetime, and 11% experienced at least two major life events during the past year. Variations in the distribution of stressors by genotype are not statistically significant. The average CES-D score by genotype is generally consistent with the presumed differences in transcriptional efficiency of the alleles. The mean for L/XL (2.9) is significantly lower (p<0.05) than those for S/S (4.7), S/L (4.9) and S/XL (5.6), but does not differ significantly from that of L/L (4.1).
