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.
