Erratum: Quantitative amyloid imaging in autosomal dominant Alzheimer's Disease: Results from the DIAN Study Group (PLoS ONE (2016) 11:3 (e0152082) DOI: 10.1371/journal.pone.0152082)

Abstract

There are errors in the published article. Incorrect sample sizes were reported in Table 4 and Table 6. The intended sample size calculation was based on two-sided two-sample t-test to estimate the number of participants per arm needed to detect the specified reduction in amyloid accumulation rate due to treatment with 80% power and two-tailed type-I error of p = 0.05 in a 12-month placebo-controlled randomized clinical trial. The tables with corrected sample size values can be seen here.(table presented).
