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

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…

Cumulative Burden of Colorectal Cancer-Associated Genetic Variants is More Strongly Associated With Early-onset vs Late-onset Cancer

Background & Aims Early-onset colorectal cancer (CRC, in persons younger than 50 years old) is increasing in incidence; yet, in the absence of a family history of CRC, this population lacks harmonized recommendations for prevention. We aimed to determine whether a polygenic risk score (PRS) developed from 95 CRC-associated common genetic risk variants was associated…

Cuestiones controvertidas en evaluación económica (III). Intervenciones sanitarias en tres situaciones especiales: enfermedades raras, tratamientos al final de la vida y externalidades en las evaluaciones

El desarrollo de la evaluación económica de intervenciones sanitarias se ha convertido en una herramienta de apoyo en la toma decisiones sobre financiación pública y fijación de precios de nuevas intervenciones sanitarias. La aplicación cada vez más extensiva de estas técnicas ha llevado a la identificación de situaciones particulares en las que, por diversas razones,…

Cuestiones controvertidas en evaluación económica (II): medidas de resultado en salud de las intervenciones sanitarias

En este segundo artículo, de una serie de tres, debatiremos, empleando la técnica Metaplan, sobre cuestiones controvertidas de las medidas de resultado en salud en la evaluación económica de intervenciones sanitarias (EEIS). Las cuatro áreas de debate se centraron en: elección de las medidas de resultado en salud: en abstracto ninguna medida es superior a…

Cruciferous Vegetable Intake and Bulky DNA Damage within Non-Smokers and Former Smokers in the Gen-Air Study (EPIC Cohort)

Epidemiologic studies have indicated that cruciferous vegetables can influence the cancer risk; therefore, we examined with a cross-sectional approach the correlation between the frequent consumption of the total cruciferous vegetables and the formation of bulky DNA damage, a biomarker of carcinogen exposure and cancer risk, in the Gen-Air study within the European Prospective Investigation into…

Cross-Cultural Adaptation, Validation, and Piloting of the Patient Reported Experiences and Outcomes of Safety in Primary Care Questionnaire for Its Use in Spain

Objective This study aimed to cross-culturally adapt, validate, and pilot the Patient Reported Experiences and Outcomes of Safety in Primary Care questionnaire for its use in Spain. Methods After setting up an expert panel to determine its content validity, the questionnaire was translated and back-translated, and subjected to cognitive testing. The questionnaire was piloted in…

Cross-cancer genome-wide analysis of lung, ovary, breast, prostate and colorectal cancer reveals novel pleiotropic associations

Identifying genetic variants with pleiotropic associations can uncover common pathways influencing multiple cancers. We took a two-staged approach to conduct genome-wide association studies for lung, ovary, breast, prostate and colorectal cancer from the GAME-ON/GECCO Network (61,851 cases, 61,820 controls) to identify pleiotropic loci. Findings were replicated in independent association studies (55,789 cases, 330,490 controls). We…

Cronicidad y uso de servicios sanitarios: la formación entre iguales de la Escuela de Pacientes

Objective: To evaluate the impact of the training strategy of the Escuela de Pacientes (School of Patients) on the use of health services among people with chronic diseases. Method: Quantitative design study of pretest and posttest evaluation with a population of 3,350 chronic patients of the Escuela de Pacientes (Andalusia, 2013-2015). A questionnaire adapted from the Stanford University was used.…
