A further critique of the analytic strategy of adjusting for covariates to identify biologic mediation
Epidemiologic Perspectives & Innovations - Tập 1 - Trang 1-13 - 2004
Epidemiologic research is often devoted to etiologic investigation, and so techniques that may facilitate mechanistic inferences are attractive. Some of these techniques rely on rigid and/or unrealistic assumptions, making the biologic inferences tenuous. The methodology investigated here is effect decomposition: the contrast between effect measures estimated with and without adjustment for one or...... hiện toàn bộ
The role of causal criteria in causal inferences: Bradford Hill's "aspects of association"
Epidemiologic Perspectives & Innovations - Tập 6 - Trang 1-22
- 2009
As noted by Wesley Salmon and many others, causal concepts are ubiquitous in every branch of theoretical science, in the practical disciplines and in everyday life. In the theoretical and practical sciences especially, people often base claims about causal relations on applications of statistical methods to data. However, the source and type of data place important constraints on the choice of sta...... hiện toàn bộ
Changes in population characteristics and their implication on public health research
Epidemiologic Perspectives & Innovations - Tập 4 - Trang 1-16 - 2007
Population estimates are generally drawn from one point in time to study disease trends over time; changes in population characteristics over time are usually not assessed and included in the study design. We evaluated whether population characteristics remained static and assessed the degree of population shifts over time. The analysis was based on the New York State 1990 and 2000 census data wit...... hiện toàn bộ
Warning: Anti-tobacco activism may be hazardous to epidemiologic scienceAbstract This commentary accompanies two articles submitted to Epidemiologic Perspectives & Innovations in response to a call for papers about threats to epidemiology or epidemiologists from organized political interests. Contrary to our expectations, we received no submissions that described threats from industry or government; all we... ... hiện toàn bộ

Generalizability in two clinical trials of Lyme disease
Epidemiologic Perspectives & Innovations - Tập 3 - Trang 1-7 - 2006
To examine the generalizability of two National Institutes of Health (NIH)-funded double-blind randomized placebo-controlled clinical trials in patients with chronic Lyme disease and to determine whether selection factors resulted in the unfavorable outcomes. Epidemiologic review of the generalizability of two trials conducted by Klempner et al. This paper considers whether the study group was rep...... hiện toàn bộ

Extending the sufficient component cause model to describe the Stable Unit Treatment Value Assumption (SUTVA)
Epidemiologic Perspectives & Innovations - Tập 9 - Trang 1-11 - 2012
Causal inference requires an understanding of the conditions under which association equals causation. The exchangeability or no confounding assumption is well known and well understood as central to this task. More recently the epidemiologic literature has described additional assumptions related to the stability of causal effects. In this paper we extend the Sufficient Component Cause Model to r...... hiện toàn bộ
Use of the integrated health interview series: trends in medical provider utilization (1972-2008)Abstract The Integrated Health Interview Series (IHIS) is a public data repository that harmonizes four decades of the National Health Interview Survey (NHIS). The NHIS is the premier source of information on the health of the U.S. population. Since 1957 the survey has collected information on health behaviors, health conditions, and health care access. The long run... ... hiện toàn bộ

Should adjustment for covariates be used in prevalence estimations?Abstract
Background
Adjustment for covariates (also called auxiliary variables in survey sampling literature) is commonly applied in health surveys to reduce the variances of the prevalence estimators. In theory, adjusted prevalence estimators are more accurate when variance components are known. In... ... hiện toàn bộ

An easy approach to the Robins-Breslow-Greenland variance estimator
Epidemiologic Perspectives & Innovations - Tập 2 - Trang 1-6
- 2005
The Mantel-Haenszel estimate for the odds ratio (and its logarithm) in stratified case control studies lacked a generally acceptable variance estimate for many years. The Robins-Breslow-Greenland estimate has met this need, but standard textbooks still do not provide an explanation of how it is derived. This article provides an accessible derivation which demonstrates the link between the Robins-B...... hiện toàn bộ
