    Författare :Tetiana Gorbach; Xavier de Luna; Anders Lundquist; Martin A. Lindquist; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Missing data; nonignorable dropout; sensitivity analysis; uncertainty intervals; pattern-mixture models; aging; cognition; MRI; brain structure; resting-state functional connectivity; Statistics; statistik;

    Sammanfattning : One of the challenges in aging research is to understand the brain mechanisms that underlie cognitive development in older adults. Such aging processes are investigated in longitudinal studies, where the within-individual changes over time are observed. However, several methodological issues exist in longitudinal analyses.

    Sammanfattning : Modeling is a valuable tool in drug development, to support decision making, improving study design, and aid in regulatory approval and labeling. This thesis describes the development of pharmacometric models for drugs used in anesthesia and analgesia. LÄS MER

  3. 3. Measuring eating disorder outcome definitions, dropout and patients' perspectives

    Detta är en avhandling från Örebro : Örebro universitet

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Medicin; Medicine;

    Sammanfattning : Background: Despite a plethora of research, there are serious limitations in our knowledge of outcome in eating disorders. Almost all studies have been compromised by the problem of treatment dropout or non-participation in follow-ups. LÄS MER

    Sammanfattning : Pharmacometric modelling is widely used in many aspects related to type 2 diabetes mellitus (T2DM), for instance in the anti-diabetes drug development, and in quantifying the disease progression of T2DM.The aim of this thesis were to improve the design of early phase anti-diabetes drug development studies with the focus on the power to identify mechanism of drug action (MoA), and to characterize and quantify the progression from prediabetes to overt diabetes, both the natural progression and the progression with diet and exercise interventions, using pharmacometrics modelling.
