===Post-study unblinding===
Post-study unblinding is the release of masked data upon completion of a study. In [[clinical studies]], post-study unblinding serves to inform subjects of their [[treatment and control groups|treatment allocation]]. Removing a blind upon completion of a study is never mandatory, but is typically performed as a courtesy to study participants. Unblinding that occurs after the conclusion of a study is not a source of bias, because data collection and analysis are both complete at this time.<ref>{{cite journal |vauthors=Dinnett EM, Mungall MM, Kent JA, Ronald ES, McIntyre KE, Anderson E, Gaw A |s2cid=36252366 |title=Unblinding of trial participants to their treatment allocation: lessons from the Prospective Study of Pravastatin in the Elderly at Risk (PROSPER) |journal=Clin Trials |volume=2 |issue=3 |pages=254–259 |date=2005 |pmid=16279148 |doi=10.1191/1740774505cn089oa }}</ref>
