Prevalence of 1q21.1 duplications in cohorts with TOF. Box size is proportional to study size: n=33,47 n=510,45 n=948,68 n=433,38 n=81,55 n=6857 and n=57.50 The blue diamond represents the combined prevalence of 1q21.1 duplications in a total of 2130 subjects with TOF, and the diamond width corresponds to 95% confidence interval bounds. In contrast, 1q21.1 duplications are rare in control populations (see text).67
