Figure 3From: A genome-wide linkage study of mammographic density, a risk factor for breast cancerManhattan plot of association test results for the square root of PMD residuals. P-values (-log10) of association tests using the orthogonal model of QTDT are plotted against physical position across the chromosomes. A Bonferroni correction for 5677 tests would lead to a threshold of 5.05 for significance at α = 0.05. PMD, percent mammographic density.Back to article page
