Differences between case and control sums of absolute correlations by time before diagnosis.

a. Controls were assigned the date of diagnosis of the case to which they were matched.b. Difference greater than 0.00 indicates absolute values of control correlations are larger than those of cases.c. If the 95% confidence interval includes zero then its corresponding p-value is not statistically significant.d. Difference less than 0.00 indicates absolute values of case correlations are larger than those among controls.e. Controls are matched to cases within three months of the time of blood draw. Therefore a matched pair may fall into separate time categories thus accounting for unequal numbers in time category.Differences between case and control sums of absolute correlations by time before diagnosis.
