Many clinical epidemiological studies investigate whether a certain exposure, or risk factor, is associated with the incidence of disease or mortality. It may be of interest to study whether this association is different in different types of patients, or to study joint effects. To investigate whether the effect of one risk factor differs across the strata of another risk factor, the presence of interaction among two risk factors can be examined. In statistics, interaction refers to the… Expand

Figures and Tables from this paper

Reporting of Interaction
Interaction is the situation whereby the association of one risk factor with a certain outcome variable differs across strata of another risk factor. From a public health perspective, the assessmentExpand
Additive influence of genetic predisposition and conventional risk factors in the incidence of coronary heart disease: a population-based study in Greece
TLDR
Genetic predisposition to CHD, operationalised through a multilocus GRS, and ConvRFs have essentially additive effects on CHD risk, suggesting that the GRS and the ConvRF do not have effects beyond additivity. Expand
Association of Patients’ Past Misdiagnosis Experiences with Trust in Their Current Physician Among Japanese Adults
TLDR
The patient’s or family members’ misdiagnosis experiences reduced trust in the patient”s current physicians, and interventions specifically targeting misdiagnosed patients are needed to restore trust. Expand
Intracerebral Hemorrhage and Outcome After Thrombolysis in Stroke Patients Using Selective Serotonin-Reuptake Inhibitors
TLDR
Preadmission treatment with SSRIs was not significantly associated with an increased risk of post-thrombolysis sICH in this cohort study, however, subgroup analysis suggested an increase in risk of sich in patients taking both SSRI and OAC. Expand
Risk of venous thrombosis in persons with increased body mass index and interactions with other genetic and acquired risk factors
TLDR
The combination of obesity, non‐O blood group and FVL increased VT risk up to ten‐fold, and identifying high VT may be beneficial in thrombosis prevention. Expand
Safety promotion and injury surveillance with special focus on young peoples club sports
TLDR
This thesis has been to identify and investigate associated risk factors related to sport injuries, and explore whether data from ambulance journals or different kinds of survey data can be used to identify injury or other health problems associated with sport, particularly affecting young people. Expand
Shared risk factors for arterial cardiovascular diseases and venous thromboembolism
TLDR
The results show that prothrombotic genotypes have an important role in the association between family history of myocardial infarction and venous thromboembolism and the prognosis for these diseases is unclear. Expand
Is “Football for All” Safe for All? Cross-Sectional Study of Disparities as Determinants of 1-Year Injury Prevalence in Youth Football Programs
TLDR
Pre-participation disparities in terms of parents’ educational level, through interaction with gender, BMI, and self-reported general health are associated with increased injury risk in community-based youth football. Expand
Do Knee Osteoarthritis and Fat‐Free Mass Interact in Their Impact on Health‐Related Quality of Life in Men? Results From a Population‐Based Cohort
TLDR
This study aims to investigate whether obesity and other risk factors interact with knee osteoarthritis in its adverse impact on health‐related quality of life (HRQOL) and to establish a causal relationship between obesity and OA. Expand
Safety promotion and injury surveillance with special focus on young people´s club sports : Challenges and possibilities
Physical activity in youth has many benefits, but parallel to these benefits, sport related injuries pose considerable risks.  It is important to public health to address sport related injuries, paExpand

The effect of joint exposures: examining the presence of interaction.
TLDR
Clinical epidemiological studies investigate whether an exposure, or risk factor, is causally related to the development or progression of a disease or mortality and whether this relation is different in different types of patients. Expand

Interaction is the situation whereby the association of one risk factor with a certain outcome variable differs across strata of another risk factor. From a public health perspective, the assessmentExpand
When One Depends on the Other: Reporting of Interaction in Case-Control and Cohort Studies
TLDR
A survey of epidemiologic studies published in leading journals found that a majority of articles reporting cohort and case-control studies address possible interactions between exposures, but in about half of these, the information provided was unsatisfactory, and only 1 in 10 studies reported data that allowed readers to interpret interaction effects on an additive and multiplicative scale.

Commentary: facing the challenge of gene-environment interaction: the two-by-four table and beyond.
TLDR
The authors propose that the two-by-four table is the fundamental unit of epidemiologic analysis, the fundamental core of gene-environment interaction, and the separate assessment of the effects of individual and joint risk factors. Expand
Concepts of interaction.
TLDR
It is proposed that synergy (or its negative counterpart, antagonism) between two or more causes of disease ought to be evaluated in reference to a specific yardstick, with effect defined as excess risk. Expand
Interaction: A word with two meanings creates confusion
TLDR
This editorial aims to provide authors with a common terminology for discussing biological and statistical interaction, and to emphasize statistical interaction in the additivemodel as the basis for assessing biological interaction. Expand
Interactions in Epidemiology: Relevance, Identification, and Estimation
TLDR
New results relating sufficient-cause models to regression models are provided and reinforce the point that concepts of biologic interaction do not in general correspond to the concept of statistical interaction, because the latter is only the need for a product term in a statistical model. Expand
Association between a self-rated health question and mortality in young and old dialysis patients: a cohort study.
TLDR
Although the SRH-mortality association remained strong despite extensive adjustments, unknown residual confounding could still exist and patient self-assessment of health can be an invaluable and economical complement to clinical measures in risk assessment. Expand

TLDR
The STROBE Statement provides guidance to authors about how to improve the reporting of observational studies and facilitates critical appraisal and interpretation of studies by reviewers, journal editors and readers. Expand
Cardiovascular outcomes and all-cause mortality: exploring the interaction between CKD and cardiovascular disease.
TLDR
CKD and CVD are both strong independent risk factors for adverse cardiovascular and mortality outcomes in the general population and although individuals with both risk factors are at extremely high risk, there does not appear to be a synergistic effect of CKD andCVD on outcomes. Expand
