Fixed versus Mixed Parameterization in Logistic Regression Models: Application to Meta-Analysis
… intercept generalized mixed model (GLMM), and conditional logistic regression (clogit) are compared in a meta-analysis of 43 studies assessing the effect of diet on cancer incidence in rats. We also perform simulation studies to assess distributional behavior of regression estimates and tests …

Residential Exposure to Non-tuberculous Mycobacteria: Sources and Associations with Pulmonary Disease
… source) were quantitatively compared in three conditional logistic regression models with varying levels of control for confounding. An age-adjusted conditional logistic regression analysis of NTM isolates from shower aerosols shows that the homes of cases had higher odds (odds ratio, 3.67, 95% …

Stroke and non-compliance with the therapeutic regimen among hypertensive men and women in Gaza Strip
… regimen, and seasonal pattern. Single logistic regression models (crude odds ratio), and multiple conditional logistic regression models were used to determine potential risk factors, which contribute to the development of stroke (medication not taking as prescribed, using excessive …

The Effect of Antidepressants on Cardiovascular Morbidity and Mortality: A Population-based Cohort Study
… of various antidepressants were estimated using conditional logistic regression and adjusted for potential confounders. Results: Compared with the current use of atypical antidepressants, current use of venlafaxine was associated with a significant reduction in the risk of MI and cardiac death …

Semiparametric Varying Coefficient Models for Matched Case-Crossover Studies
… effect on independent predictors included in the conditional logistic regression model. Any stratum effect is removed by the conditioning on the fixed number of sets of the case and controls in the stratum. However, some matching covariates such as time, and/or spatial location often play an …

Hypogonadism, Testosterone Replacement Therapy and Risk of Depression in Middle Aged and Older Men in the US
… by age and hypogonadal status. Separate conditional logistic regression models tested whether a) hypogonadism is associated with increased odds of incident depression and b) exposure to TRT in hypogonadal men is associated with reduced odds of incident depression. Cox proportional hazards …

Hospital Fall Prevention Using Interactive Patient Care Technology
… assessment tool, r (118) = .45, p < .001. Using conditional logistic regression, length of stay, number of automatic video prompts, and fall prevention video completion status were significantly associated with a hospital fall. As length of stay increased by one day, the odds of a fall were 11% …

Evaluation of the Role of Adjunctive Corticosteroids in the Management of Children Hospitalized with Orbital Cellulitis
… using generalized linear mixed-effects or conditional logistic regression modeling to assess for differences in outcomes including length of stay (LOS), cost, intensive care unit (ICU) transfer, emergency department (ED) revisits, and hospital readmissions between children who did or did …

Neurologic And Metabolic Safety Of Fluoroquinolones
… Chapter 2, our outcome was serious hypoglycemia. Conditional logistic regression was conducted after matching. The odds ratios associated with fluoroquinolone exposure were 1.30 (95% CI: 1.05-1.62) among individuals with diabetes and 1.06 (95% CI: 0.53-2.13) in those without diabetes. In Chapter …

Predictors Of Use Of Hydroxyurea And Its Impact On Clinical And Economic Outcomes Among Children With Sickle Cell Disease
… emergency department visits were assessed using conditional logistic regression stratified on matched pairs. Length of stay and medical costs were compared in the matched sample using generalized linear models. An additional clinical outcome, number of crises, was evaluated in the unmatched …

The roles of genetics and glycaemic control in the development of LVH and Heart Failure in Type 2 Diabetes
… mean HbA1C was calculated for each of them. Logistic regression analysis and proportional hazard regression analysis were performed to investigate whether glycaemic control was independently related to LVH and HF. Genetic typing for published loci associated with glycaemic control was …

The association between air pollution and lung cancer in the north west of Adelaide: a case control study and air quality monitoring.
… Data was analysed utilising chi- quared and conditional logistic regression. Ambient carcinogens and fine particulates with potential industrial sources in the region were monitored in five locations. In the final multivariate model leaving school early, pack- years of cigarettes and not …
