TLDR
Artificial neural networks are algorithms that can be used to perform nonlinear statistical modeling and provide a new alternative to logistic regression, the most commonly used method for developing predictive models in medicine. Expand

A population-based study of the drug interaction between proton pump inhibitors and clopidogrel
Background: Most proton pump inhibitors inhibit the bioactivation of clopidogrel to its active metabolite. The clinical significance of this drug interaction is unknown. Methods: We conducted aExpand

Deriving Ethnic-Specific BMI Cutoff Points for Assessing Diabetes Risk
OBJECTIVE The definition of obesity (BMI ≥30 kg/m2), a key risk factor of diabetes, is widely used in white populations; however, its appropriateness in nonwhite populations has been questioned. WeExpand

Effects of socioeconomic status on access to invasive cardiac procedures and on mortality after acute myocardial infarction.
BACKGROUND Universal health care systems seek to ensure access to care on the basis of need rather than income and to improve the health status of all citizens. We examined the performance of theExpand

Safety and Efficacy of Drug-Eluting and Bare Metal Stents: Comprehensive Meta-Analysis of Randomized Trials and Observational Studies
Background— The safety and efficacy of drug-eluting stents (DES) among more generalized “real-world” patients than those enrolled in pivotal randomized controlled trials (RCTs) are controversial. WeExpand

Relation of Disease Pathogenesis and Risk Factors to Heart Failure With Preserved or Reduced Ejection Fraction: Insights From the Framingham Heart Study of the National Heart, Lung, and Blood
Background— The contributions of risk factors and disease pathogenesis to heart failure with preserved ejection fraction (HFPEF) versus heart failure with reduced ejection fraction (HFREF) have notExpand
