cvauroc: Command to compute cross-validated area under the curve for ROC analysis after predictive modeling for binary outcomes

Artículos Científicos

Receiver operating characteristic (ROC) analysis is used for comparing predictive models in both model selection and model evaluation. ROC analysis is often applied in clinical medicine and social science to assess the tradeoff between model sensitivity and specificity. After fitting a binary logistic or probit regression model with a set of independent variables, the predictive…

Risk of suicide in households threatened with eviction: the role of banks and social support

Artículos Científicos

Background One of the greatest effects of the financial crisis in Spain has been the enormous increase in the number of evictions. Several studies have shown the association of evictions with different aspects of the physical and mental health. Furthermore, evictions have been associated with an increased risk of suicide. Our objective was to evaluate…

Exogenous Hormone Use and Cutaneous Melanoma Risk in Women: The European Prospective Investigation Into Cancer and Nutrition

Artículos Científicos

Evidence suggests an influence of sex hormones on cutaneous melanoma risk, but epidemiologic findings are conflicting. We examined the associations between use of oral contraceptives (OCs) and menopausal hormone therapy (MHT) and melanoma risk in women participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is a prospective cohort study initiated in…

Association Between Soft Drink Consumption and Mortality in 10 European Countries

Artículos Científicos

Importance  Soft drinks are frequently consumed, but whether this consumption is associated with mortality risk is unknown and has been understudied in European populations to date. Objective  To examine the association between total, sugar-sweetened, and artificially sweetened soft drink consumption and subsequent total and cause-specific mortality. Design, Setting, and Participants  This population-based cohort study involved…

Using longitudinal targeted maximum likelihood estimation in complex settings with dynamic interventions

Artículos Científicos

Longitudinal targeted maximum likelihood estimation (LTMLE) has very rarely been used to estimate dynamic treatment effects in the context of time‐dependent confounding affected by prior treatment when faced with long follow‐up times, multiple time‐varying confounders, and complex associational relationships simultaneously. Reasons for this include the potential computational burden, technical challenges, restricted modeling options for long…

Vitamin D-Related Genes, Blood Vitamin D Levels and Colorectal Cancer Risk in Western European Populations

Artículos Científicos

Higher circulating 25-hydroxyvitamin D levels (25(OH)D) have been found to be associated with lower risk for colorectal cancer (CRC) in prospective studies. Whether this association is modified by genetic variation in genes related to vitamin D metabolism and action has not been well studied in humans. We investigated 1307 functional and tagging single-nucleotide polymorphisms (SNPs;…

Pre-diagnostic plasma bile acid levels and colon cancer risk: A prospective study

Artículos Científicos

Background Bile acids have been proposed to promote colon carcinogenesis. However, there are limited prospective data on circulating bile acid levels and colon cancer risk in humans. Methods Associations between pre-diagnostic plasma levels of 17 primary, secondary and tertiary bile acid metabolites (conjugated and unconjugated) and colon cancer risk were evaluated in a nested case-control…

Estimated Substitution of Tea or Coffee for Sugar-Sweetened Beverages Was Associated with Lower Type 2 Diabetes Incidence in Case–Cohort Analysis across 8 European Countries in the EPIC-InterAct Study

Artículos Científicos

Introduction Beverage consumption is a modifiable risk factor for type 2 diabetes (T2D), but there is insufficient evidence to inform the suitability of substituting 1 type of beverage for another. Objective The aim of this study was to estimate the risk of T2D when consumption of sugar-sweetened beverages (SSBs) was replaced with consumption of fruit…

Intimate Partner Violence During Pregnancy and Risk of Fetal and Neonatal Death: A Meta-Analysis with Socioeconomic Context Indicators

Artículos Científicos

Objective To summarize the results from observational studies examining the risk of fetal and neonatal death (perinatal death) as a function of the experience of Intimate Partner Violence (IPV) during pregnancy and examine the influence of socioeconomic context indicators on this association. Data sources Bibliographic searches were conducted in PubMed, EMBASE, CINAHL, and LILACS until…
