Educational Note: Paradoxical collider effect in the analysis of non-communicable disease epidemiological data: a reproducible illustration and web application

Artículos Científicos

Classical epidemiology has focused on the control of confounding, but it is only recently that epidemiologists have started to focus on the bias produced by colliders. A collider for a certain pair of variables (e.g. an outcome Y and an exposure A) is a third variable (C) that is caused by both. In a directed…

Social support buffers the negative effects of stress in cardiac patients: a cross-sectional study with acute coronary syndrome patients

Artículos Científicos

Cardiac patients who have social support generally have better prognosis than patients who lack social support. Several theoretical mechanisms have been proposed to explain this protective effect, including the capacity of social support to buffer the negative effects of stress. We tested this buffering effect in a study of patients hospitalized for acute coronary syndrome…

Interaction between MTHFR 677C>T, PON1 192Q>R and PON1 55L>M polymorphisms and its effect on non-recurrent spontaneous abortion in Mexican women

Artículos Científicos

MTHFR is a key enzyme in folate metabolism. Some genetic polymorphisms code for a less efficient enzyme, increasing serum concentrations of homocysteine. This has been associated with inadequate feto-maternal circulation and increased risk of spontaneous abortion. Paroxonase 1 (PON1) is a multifunctional enzyme that can detoxify homocysteine through its homocysteine thiolactonase activity. We evaluate the…

Coffee and tea drinking in relation to the risk of differentiated thyroid carcinoma: results from the European Prospective Investigation into Cancer and Nutrition (EPIC) study

Artículos Científicos

Purpose Coffee and tea constituents have shown several anti-carcinogenic activities in cellular and animal studies, including against thyroid cancer (TC). However, epidemiological evidence is still limited and inconsistent. Therefore, we aimed to investigate this association in a large prospective study. Methods The study was conducted in the EPIC (European Prospective Investigation into Cancer and Nutrition)…

KIM-1 as a Blood-Based Marker for Early Detection of Kidney Cancer: A Prospective Nested Case–Control Study

Artículos Científicos

Purpose: Renal cell carcinoma (RCC) has the potential for cure with surgery when diagnosed at an early stage. Kidney injury molecule-1 (KIM-1) has been shown to be elevated in the plasma of RCC patients. We aimed to test whether plasma KIM-1 could represent a means of detecting RCC prior to clinical diagnosis. Experimental Design: KIM-1…

Risk prediction for estrogen receptor-specific breast cancers in two large prospective cohorts

Artículos Científicos

Background Few published breast cancer (BC) risk prediction models consider the heterogeneity of predictor variables between estrogen-receptor positive (ER+) and negative (ER-) tumors. Using data from two large cohorts, we examined whether modeling this heterogeneity could improve prediction. Methods We built two models, for ER+ (ModelER+) and ER- tumors (ModelER-), respectively, in 281,330 women (51%…

How are risk ratios reported in orthopaedic surgery journals? A descriptive study of formats used to report absolute risks

Artículos Científicos

Purpose The numerical format in which risks are communicated can affect risk comprehension and perceptions of medical professionals. We investigated what numerical formats are used to report absolute risks in empirical articles, estimated the frequency of biasing formats and rated the quality of figures used to display the risks. Design Descriptive study of reporting practices.…
