AbstractMethods. aEuro integral Sonographers were assessed for measures of central tendency and dispersion by comparing them with expected population median and dispersion parameters. NT measurements were converted to multiples of the expected NT values according to CRL (NTMoM) and transformed to their log(10) equivalent (log(10) NTMoM). Central tendency and measurement were assessed by checking whether the median of the NTMoM distribution and SD of the log(10) NTMoM distributions were, respectively, within 5%% or 10%% of the expected median of 1 and SD of 0.1. Assessment was performed using both the Center specific and Fetal Medicine Foundation (FMF) reference NT for Crown rump length (CRL).
