Correction: Reduction of late stillbirth with the introduction of fetal movement information and guidelines - a clinical quality improvement

The validation procedures revealed inaccuracies in data from the Medical Birth Registry of Norway for a partial comparison with mortality outside the study area, and we here correct this comparison. We present new, corrected and cross-validated data. Despite comparability issues, the most robust and cross-validated estimates confirm similar estimates of reduced mortality during the quality improvement intervention.This article is based on the clinical Femina data collection - independent of the Medical Birth Registry of Norway (MBRN). However, a partial comparison with the population outside the cohort was included, using MBRN data (1).In accordance with the study protocol of 2005, we aimed to compare our Femina data with MBRN data for the full cohort for an independent validation of stillbirth rates in the total population. The complete data set for Norway for 2007, needed for this final comparison, was released by the MBRN on December 13, 2009. Upon receipt of these complete data we found discrepancies with the data our project had previously received from the MBRN and published (1). The MBRN performed an inquiry into the two data deliveries, and on February, 17, 2010, the MBRN issued a public report which confirmed that the previous data delivery to our project was inaccurate.We deeply regret this, and wish to correct the original article accordingly and provide new and validated data.From the section Data collection, the following sentence describes the data found to be inaccurate, and should be discarded: "In addition to the registrations by our study protocol, the numbers of births and stillbirths from our population were obtained from the Medical Birth Registry in Norway to assess overall trends in stillbirth, for the most updated period available: April 2005 to December 2006."From the third paragraph of the Results section, the following sentence is based on the inaccurate data, and should be discarded: "Independent data from the Medical Birth Registry in No
