The diagnostic utility of procalcitonin, interleukin-6 and interleukin-8, and hyaluronic acid in the Norwegian consensus definition for early-onset neonatal sepsis (EONS) [Retraction] Nakstad B. The diagnostic utility of procalcitonin, interleukin- 6 and interleukin-8, and hyaluronic acid in the Norwegianconsensus definition for early-onset neonatal sepsis (EONS). Infection and Drug Resistance. 2018:11;359–368.At the request of the author, the Editor-in-Chief and Publisher of the Infection and Drug Resistance wish to retractthe published article. On review of a previous draft and the published article the author noticed both versions had identical correlation, r and significance values, p in the results section “Overall response in soluble biomarkers”. The raw data sets used in both versions were not identical and it was not possible for both data sets to produce the same correlation and significance values. A recalculation of the raw data set used for the published version showed no correlation in neonatal plasma betweenPCT and IL-8 and PCT and IL-6 which differed considerably to the positive correlation result presented in the publishedarticle. Additionally, some of the patients reported with positive blood culture were older than 72 h at onset of symptomsand should not have been included as early-onset neonatal sepsis (EONS) patients. Therefore, the findings and recommendations presented in the article are not supported.The author wishes to apologize for the error. The original article has been Retracted
