1. Chronic myeloid leukemia and cancer
Sammanfattning : Background Chronic myeloid leukemia (CML) is a relatively rare hematological malignancy with a constant incidence of approximately 90 new cases each year in Sweden (0.9 cases/100 000 inhabitants). The etiology is largely unknown but high doses of ionizing radiation are a known but rare risk factor. LÄS MER
2. Epidemiological aspects of musculoskeletal pain in the upper body. Analyzing common and recurrent binary outcomes
Sammanfattning : The overall aim of this thesis is to gain epidemiological knowledge about musculoskeletal pain in the upper body in light physical work, in relation to gender, psychosocial factors, and computer use; and to compare different methods for analyzing common and recurrent binary outcomes. Two study groups were investigated using questionnaire data: (a) computer users in the Swedish workforce and (b) a cohort of university students. LÄS MER
3. Methodological Studies on Models and Methods for Mixed-Effects Categorical Data Analysis
Sammanfattning : Effects of drugs are in clinical trials often measured on categorical scales. These measurements are increasingly being analyzed using mixed-effects logistic regression. However, the experience with such analyzes is limited and only a few models are used. LÄS MER
4. Optimal Design and Inference for Correlated Bernoulli Variables using a Simplified Cox Model
Sammanfattning : This thesis proposes a simplification of the model for dependent Bernoulli variables presented in Cox and Snell (1989). The simplified model, referred to as the simplified Cox model, is developed for identically distributed and dependent Bernoulli variables. LÄS MER
5. Dietary exposure to persistent organochlorine compounds and health effects in women and their infants - Epidemiological studies on birthweight, cancer incidence, and mortality
Sammanfattning : In Sweden the main exposure route for both polychlorinated biphenyls (PCB) and other persistent organochlorine compounds is through consumption of fatty fish species from the Baltic Sea (the eastern coast of Sweden). Cohorts of fishermen's wives from the Swedish east and west coasts were established. LÄS MER
