Common two-phase designs include nested case-control and case-cohort designs. Additional designs include sampling subjects based on follow-up time, like extreme case-control designs. Recently an ...

This paper tackles perhaps the two most common control co-design coordination strategies: simultaneous analysis and design and the nested control problem formulation. Many practical insights into the ...

The study design is a prospective nested case–control study, which can minimise the selection bias and missing data. This study will adopt the artificial neural networks approach to construct the ...

Objective Evaluate the risk of pre-existing comorbidities on COVID-19 mortality, and provide clinical suggestions accordingly. Setting A nested case–control design using confirmed case reports ...

Methods Design: Nested case-control study. Population: consecutive RA-patients (ACR/EULAR 2010 criteria), >16 years, selected from a prospective inception cohort (diagnosis of RA between 2007 and 2011 ...

Background Milk curd obstruction (MCO), in which milk becomes inspissated, is a rare, serious, complication of preterm birth. Case reports implicate male sex and bovine-derived human milk fortifier ...

This study aimed to elucidate the association between the Dietary Antioxidant Index (DAI) and hypertension risk using a nested case–control design. Method: A matched nested case–control study was ...

Secondly, the nested case-control design ensures that exposure (gut virome) precedes outcome (GDM). Thirdly, our findings were reinforced by a GDM prediction model incorporating early pregnancy gut ...

In a large (n = 624 cases) nested case-control study, we investigated the association between 152 circulating inflammatory and immune response protein biomarkers and the risk of endometrial cancer. We ...

The course will present statistical approaches that enable researchers to design more efficient case-control studies and to exploit more efficiently the data provided by nested case-control studies ...

Methods In a case–control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC), we examined associations between pre-diagnostic circulating concentrations of 97 ...

This observational study explored the risk of major adverse cardiovascular events (MACEs) associated with angiogenesis inhibitors in Taiwan. We conducted a nested case-control study using the TCR ...
