Although selecting a probability sample has been the standard for decades when making inferences from to finite population, incentives are increasing use nonprobability samples. In world of “big data”, large amounts data available that faster and easier collect than Design-based inference, in which distribution inference is generated by random mechanism used sampler, cannot be One alternative quasi-randomization pseudo-inclusion probabilities estimated based on covariates samples nonsample...
Emerging evidence suggests many people have persistent symptoms after acute coronavirus disease 2019 (COVID-19) illness. Our objective was to estimate the prevalence and correlates of post-acute sequelae severe respiratory syndrome 2 (SARS-CoV-2) infection (PASC).We used a population-based probability survey adults with COVID-19 in Michigan. Living noninstitutionalized aged ≥18 Michigan Disease Surveillance System onset through mid-April 2020 were eligible for selection (N = 28 000). Among...

A sudden loss of wealth-a negative wealth shock-may lead to a significant mental health toll and also leave fewer monetary resources for health-related expenses. With limited years remaining regain lost in older age, the consequences these shocks may be long-lasting.To determine whether shock was associated with all-cause mortality during 20 follow-up.The Health Retirement Study, nationally representative prospective cohort study US adults aged 51 through 61 at entry. The population included...
Over the last two decades, research has assessed relationship between neighborhood socioeconomic factors and individual health. However, existing is based almost exclusively on cross-sectional data, ignoring complexity in health transitions that may be shaped by long-term residential exposures. We address these limitations specifying distinct over multiple waves of a 15-year study American adults. focus hierarchy states, (free from problems, onset death), not just gradients single indicator...
We assessed the long-term effect of early childhood lead exposure on academic achievement in mathematics, science, and reading among elementary junior high school children.We linked blood testing surveillance data from Detroit Department Health Wellness Promotion to educational Detroit, Michigan, public schools. used investigate school-aged children, both marginally adjusted for grade level, gender, race, language, maternal education, socioeconomic status.High levels before age 6 years were...
We analyzed urban-rural differences in intentional firearm death.We 584629 deaths from 1989 to 1999 assigned 3141 US counties, using negative binomial regressions and an 11-category variable.The most urban counties had 1.03 (95% confidence interval [CI]=0.87, 1.20) times the adjusted death rate of rural counties. The experienced 1.54 CI=1.29, 1.83) suicide urban. 1.90 CI=1.50, 2.40) homicide rural. Similar opposing trends were not found for nonfirearm or homicide.Firearm is as important a...
In assessing the mechanism of treatment efficacy in randomized clinical trials, investigators often perform mediation analyses by analyzing if significant intent-to-treat effect on outcome occurs through or around a third intermediate mediating variable: indirect and direct effects, respectively. Standard assume sequential ignorability, i.e. conditional covariates factor is randomly assigned, as trial. This research focuses application principal stratification (PS) approach for estimating...

The relationships 2 independent variables interest, consumption outlet availability, outcome gun were analyzed. Conditional logistic regression used adjust for...
<h3>Importance</h3> Attention-deficit/hyperactivity disorder (ADHD) often persists into adolescence, when motor vehicle crash risk peaks. We know little about adolescents with ADHD get licensed and, once they do, the extent to which have increased compared without ADHD. <h3>Objectives</h3> To examine association between and both driver licensing involvement whether it varies by sex, age, and/or being prescribed medication at licensure. <h3>Design, Setting, Participants</h3> This...
Valid causal inference from observational studies requires controlling for confounders. When time-dependent confounders are present that serve as mediators of treatment effects and affect future assignment, standard regression methods fail. Similar issues also arise in trials with sequential randomization, when randomization at later time points is based on intermediate outcomes earlier randomized assignments. We propose a robust multiple imputation-based approach to this setting called...

BACKGROUND. Motor vehicle crashes are the leading cause of fatality and acquired disability in adolescents. Young, inexperienced drivers overrepresented crashes. OBJECTIVE. Our goal was to explore adolescent perspective on driving safety provide a better understanding factors that influence teenagers' exposure hazards. METHODS. Adolescents generated, prioritized, explained their viewpoint by using teen-centered method. These viewpoints were obtained from school-based nationally...

Summary A surrogate marker ( S ) is a variable that can be measured earlier and often more easily than the true endpoint T in clinical trial. Most previous research has been devoted to developing surrogacy measures quantify how well replace or examining use of predicting effect treatment Z ). However, requires one fit models for distribution given . It known such do not have causal interpretations because condition on postrandomization In this article, we directly model relationship among ,...
Patterns of symptom clustering in midlife women may suggest common underlying mechanisms or identify at risk adverse health outcomes or, conversely, likely to experience healthy aging. This paper assesses the Study Women's Health Across Nation (SWAN) longitudinally by stage reproductive aging and estimates probability experiencing specific clusters. We also evaluate factors that influence likelihood clusters assess whether is associated with women's self-reported status. analysis includes...
Surveys are experiencing declining response rates. With more and effort expended to combat these rates, the cost of large-scale surveys has continued rise. Stopping rules one interventions used improve efficiency data collection. However, most previously proposed stopping have focused only on quality a single estimate or assumed sufficient funds for nonresponse follow-up. In multipurpose surveys, there may be objectives that must met multiple estimates with constraint costs. this paper, we...
Epithelial ovarian cancer (EOC) cells seed at mesothelial inflammation or injury sites. Lack of animal models recapitulating tumor seeding inflamed sites in EOC hinders mechanistic studies and therapy developments. Here, we developed a non-surgical MIM (Mesothelium Inflammation/Injury Metastasis) model that recapitulates cell This captures temporal changes immune microenvironment growth allowing for deeper preclinical therapeutic in-vivo. We show here HGS-3 high-grade murine serous...
This article reports on the data collected one of most ambitious government‐sponsored environmental acquisition projects all time, Risk Management Plan (RMP) under section 112(r) Clean Air Act Amendments 1990. RMP Rule was triggered by Bhopal accident in 1984 and led to requirement that each qualifying facility develop file with U.S. Environmental Protection Agency a as well history for five‐year period preceding filing RMP. These were 1999–2001 more than 15,000 facilities United States...
