recommendations! Published in 2021 at "Journal of clinical epidemiology"

DOI: 10.1016/j.jclinepi.2021.08.028

Abstract: Observational databases are often used to study causal questions. Before being granted access to data or funding, researchers may need to prove that "the statistical power of their analysis will be high". Analyses expected to… read more here.
