  1. 1. Semiparametric survival models for routine register data

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Frank Eriksson; Göteborgs universitet.; Gothenburg University.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Survival; transformation; clustered; likelihood; random effects; case-cohort; routine register; semiparametric;

    Sammanfattning : Routine registers offer researchers opportunities to carry out studies of covariate effects on lifetimes of rare diseases otherwise infeasible because of the large cohorts required. Familial relationships necessary for analysis of environmental or genetic factors can be identified by record linking. LÄS MER

  2. 2. Correlated random effects models for clustered survival data

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Frank Eriksson; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Survival analysis; frailty model; competing risks; random effects; case-cohort; routine register; semiparametric; competing risks; case-cohort; semiparametric; Survival analysis; random effects; routine register; frailty model;

    Sammanfattning : Frailty models are frequently used to analyse clustered survival data in medical contexts. The frailties, or random effects, are used to model the association between individual survival times within clusters. LÄS MER

  4. 4. Vaginal prolapse surgery an epidemiological perspective : studies of native tissue repair versus implants, surgeons´ practical experiences and five year follow-up in the swedish national quality register for gynecological surgery

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Emil Nüssler; Umeå universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pelvic organ prolapse; Kaplan-Meier curves; long-term follow-up; quality register; questionnaire; patient reported outcome; cystocele; rectocele; colporrhaphy; non-absorbable mesh; surgical experience; health services research; hälso- och sjukvårdsforskning; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Background: Pelvic organ prolapse (POP) is a common condition that impacts on quality of life for many women. The mean age of Swedish women operated for POP is 60 years, and with a life expectancy of approximately 84 years this means that the average patient will live 24 years subsequent to the operation.

  5. 5. [18F]Flutemetamol PET image processing, visualization and quantification targeting clinical routine

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Lilja; Uppsala universitet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; quantification; flutemetamol; amyloid imaging; Alzheimer’s disease; positron emission tomography; brain mapping; stereotactic surface projections; image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Alzheimer’s disease (AD) is the leading cause of dementia and is alone responsible for 60-70% of all cases of dementia. Though sharing clinical symptoms with other types of dementia, the hallmarks of AD are the abundance of extracellular depositions of β-amyloid (Aβ) plaques, intracellular neurofibrillary tangles of hyper phosphorylated tau proteins and synaptic depletion.
