2. 1. Chronic myeloid leukemia and cancer

   Author : Niklas Gunnarsson; Anders Själander; Martin Höglund; Bertil Lindahl; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic myeloid leukemia; Prevalence; Malignancies; Odds ratio; Standardized Incidence Ratio; Outcome; Autoimmune diseases; Survival; Epidemiology; epidemiologi; medicin; Medicine;

   Abstract : 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. READ MORE

4. 2. Epidemiological aspects of musculoskeletal pain in the upper body. Analyzing common and recurrent binary outcomes

   Author : Anna Grimby-Ekman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; musculoskeletal; pain; neck; repeated measurements; logistic model; odds ratio OR ; risk ratio RR ; risk difference RD ; biological interaction;

   Abstract : 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. READ MORE

5. 3. Methodological Studies on Models and Methods for Mixed-Effects Categorical Data Analysis

   Author : Maria C. Kjellsson; Mats O. Karlsson; Siv Jönsson; Gordon Graham; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacodynamics; Categorical data; Markov model; Modelling; NONMEM; NLMIXED; Laplace; Gaussian quadrature; Back-Step Method; Proportional odds model; Differential odds model;

   Abstract : 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. READ MORE

6. 4. Optimal Design and Inference for Correlated Bernoulli Variables using a Simplified Cox Model

   Author : Daniel Bruce; Hans Nyquist; Werner G. Müller; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cox binary model; correlated binary data; log-odds ratio; D-optimality; E-optimality; power maximization; efficiency; Statistics; Statistik; statistik; Statistics;

   Abstract : 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. READ MORE

7. 5. Dietary exposure to persistent organochlorine compounds and health effects in women and their infants - Epidemiological studies on birthweight, cancer incidence, and mortality

   Author : Lars Rylander; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birthweight; breast cancer; ischemic heart disease; n-3 polyunsaturated fatty acids; CB-153; PCB; dibenzofurans; dioxins; fish consumption; persistent organochlorine compounds; gender ratio; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

   Abstract : 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. READ MORE
