Erratum to: Changing rates of physical and psychosocial impairments over 9 years in cohorts of school beginners in Germany

Abstract

[Extract] Some results of the article by Caniato et al. titled “Changing rates of physical and psychosocial impairments over 9 years in cohorts of school beginners in Germany” (Caniato et al. 2009) have to be revised due to partial data coding problems during electronic data processing producing mainly underestimated prevalence rates of impairments. Due to this problem, we underestimated prevalence rates of impairments in a number of domains, especially in rates of male motor disorders and in cognitive impairments for both males and females.
