Efficiency of two-phase methods with focus on a planned population-based case-control study on air pollution and stroke

BACKGROUND: We plan to conduct a case-control study to investigate whether exposure to nitrogen dioxide (NO(2)) increases the risk of stroke. In case-control studies, selective participation can lead to bias and loss of efficiency. A two-phase design can reduce bias and improve efficiency by combini...
