21. Stroke in elderly people. A randomised study of stroke unit care. Evaluation of health care utilisation and costs
Sammanfattning : The overall aim of this thesis was to evaluate stroke unit care for elderly patients, aged > 70 years, in daily life activities, health-related quality of life and costs, to describe patients´ conditions from the perspectives of re-admissions to hospital care and to identify the consequences of cognitive impairments on daily life activities and costs.I-II.

22. Optimization of paediatric CT examinations - An approach to minimize absorbed dose to patients with regard to image quality and observer variability
Sammanfattning : The absorbed dose to paediatric patients is important bearing in mind the increased risk of radiation-induced cancer due to exposure to X-rays at young ages. Questions have also been raised of whether a CT examination of the paediatric brain might lead to a reduction in cognitive function. LÄS MER
23. Learning local predictive accuracy for expert evaluation and forecast combination
Sammanfattning : This thesis consists of four papers that study several topics related to expert evaluation and aggregation. Paper I explores the properties of Bayes factors. Bayes factors, which are used for Bayesian hypothesis testing as well as to aggregate models using Bayesian model averaging, are sometimes observed to behave erratically. LÄS MER
24. Quantifying Gait Characteristics and Neurological Effects in people with Spinal Cord Injury using Data-Driven Techniques
Sammanfattning : Spinal cord injury, whether traumatic or nontraumatic, can partially or completely damage sensorimotor pathways between the brain and the body, leading to heterogeneous gait abnormalities. Mobility impairments also depend on other factors such as age, weight, time since injury, pain, and walking aids used. LÄS MER
