  • Table 2 compares mean slope of carriers detected in quarter-year windows, adjusted for the total BRCA carriers in the population living in the four different London areas. P values of Mann Whitney U tests are given in the different cells. The top half of the table reflects data for the general population and the bottom half data for the Jewish population.
