 \begin{document}
 
+The identification strategy centers on the fact that, in the U.S., clinical trials
+update the publically available information on \url{ClinicalTrials.gov}, which are available
+as historical snapshots through the website.
+These updates typically include information such as additional sites conducting the study, 
+the study status, and expected or current enrollment figures. 
+By measuring enrollment and other factors prior to the conclusion of a trial, we 
+can measure the effect of enrollment on trial conclusion 
+(specifically whether it is registered as completed or terminated).
+In particular, this avoids measuring the joint determination of enrollment and conclusion
+status arising from trials terminated early.
+Figure \cref{Fig:CausalModel} describes the structural causal model used to justify
+our identification claims.
