Hypertension and diabetes incidence: confounding factors [PDF]

Hypertension Research, 2011
Multimorbidity, defined as the coexistence of two or more chronic diseases, is a common phenomenon. Numerous efforts to establish a standardized instrument to assess the level of multimorbidity have failed until now, and indices are primarily characterized by their high heterogeneity.

Confounding Factors in the Interpretation of Preclinical Studies [PDF]

International Journal of Toxicology, 2019
A number of issues may arise during the conduct of a study which can complicate interpretation of in vitro and in vivo datasets. Speakers discussed the implications of differing interpretations and how to avoid complicating factors during study planning and execution. Consideration needs to be given to study design factors including defining objectives,

Recommendations for using standardised phenotypes in genetic association studies

Human Genomics, 2009
Genetic association studies of complex traits often rely on standardised quantitative phenotypes, such as percentage of predicted forced expiratory volume and body mass index to measure an underlying trait of interest (eg lung function, obesity).

Confounding factors and seasonal depression

International Journal of Circumpolar Health, 2003
While reviewing the literature about seasonal affective disorder, we read about the work by Nilsson and collaborators (1999), showing that the rate of self reported depression was four to five times higher in Russians than in Norwegians living on Svalbard.

Safety and Effectiveness of a High‐Dose, Tailored Tissue Plasminogen Activator Therapy Protocol: A Joint Pediatric Hematology and Cardiac ICU Quality Improvement Initiative Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA
