Numerous studies have demonstrated heightened prevalence of depressive and anxiety disorders lesbian, gay, bisexual groups as compared with heterosexuals. Some authors posit that these the result stress prejudice perceived discrimination can cause. The current study extends previous research by examining associations between multiple types discrimination, based on race or ethnicity,...
Many applied researchers analyzing longitudinal data share a common misconception: that specialized statistical software is necessary to fit hierarchical linear models (also known as mixed [LMMs], or multilevel models) sets. Although several programs of high quality are available allow these sets (e.g., HLM), rapid advances in general purpose packages have recently enabled analysts same when using preferred also enable other more analyses. One SPSS, which includes very flexible and powerful...
Abstract Ipilimumab, an antibody that enhances T‐cell activation, may augment immunogenicity of tumor cells are injured by radiation therapy. We hypothesized patients with melanoma brain metastasis treated both ipilimumab and radiotherapy would have improved overall survival, the sequence treatments affect disease control in brain. analyzed clinical radiographic records metastases who were whole therapy or stereotactic radiosurgery between 2005 2012. The hazard ratios for survival estimated...
There is consensus in the research literature that substance use disparities exist among sexual minority women and men; however, few studies have examined risk factors may contribute to these disparities.To compare reports of life-time victimization experiences a US national sample adult heterosexual men examine relationships between past-year disorders.The secondary data analyses used 2004-05 (wave 2) National Epidemiologic Survey on Alcohol Related Conditions (NESARC) collected structured...

Given the limited understanding these among adolescents, we examine high school seniors between 1976 2015.The data used for study come from Monitoring Future adolescents. Forty cohorts nationally representative samples (modal age 18) were to self-reported opioids.Lifetime prevalence peaked both 1989 2002 remained stable until a recent decline 2013 through 2015. Lifetime was less...

Abstract Objectives: The objectives were to describe presentation characteristics and health care utilization information pertaining dizziness presentations in U.S. emergency departments (EDs) from 1995 through 2004. Methods: From the National Hospital Ambulatory Medical Care Survey (NHAMCS), patient visits EDs for “vertigo‐dizziness” identified. Sample data weighted produce nationally representative estimates. Patient characteristics, diagnoses, obtained. Trends over time assessed using...

In recent years, general-purpose statistical software packages have incorporated new procedures that feature several useful options for design-based analysis of complex-sample survey data. A common and frequently desired technique data in practice is the restriction estimation to a subpopulation interest. These subpopulations are often referred interchangeably variety fields as subclasses, subgroups, domains. this article, we consider two approaches analysts can follow when analyzing...
