^aPercentages represent women who responded that women should begin screening between ages 40 and 44 years.

^bWomen were asked to select an age at which they should stop receiving a mammogram or whether they should never stop.

^cPercentages represent women who disagreed with this statement.

^dP values from chi-square tests (two-sided) for overall race effect followed by pairwise comparisons between races. A significance level of 0.05 was used for the overall race comparisons. Bonferroni adjustments created a significance level of 0.05/3 = 0.0167 for each pairwise comparison.
