      <p><i>Context - </i>Application of ultrasound (US) to evaluate attainment and morphology of glandular tissue provides a new rationale for evaluating onset and progression of female puberty, but currently no hormone references complement this method. Furthermore, previous studies have not explored the predictive value of endocrine profiling to determine female puberty onset. <p><i>Objective - </i>To ...
    • Reference curves for pediatric endocrinology: leveraging biomarker z-scores for clinical classifications 

      Madsen, Andre; Almås, Bjørg; Bruserud, Ingvild Særvold; Oehme, Ninnie Helen Bakken; Nielsen, Christopher Sivert; Roelants, Mathieu; Hundhausen, Thomas Eckhard; Ljubicic, Marie Lindhardt; Bjerknes, Robert; Mellgren, Gunnar; Sagen, Jørn V.; Juliusson, Pétur Benedikt; Viste, Kristin (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-17)
      Context: Hormone reference intervals in pediatric endocrinology are traditionally partitioned by age and lack the framework for benchmarking individual blood test results as normalized z-scores and plotting sequential measurements onto a chart. Reference curve modeling is applicable to endocrine variables and represents a standardized method to account for variation with gender and age.<p> <p>Objective: ...
