Study ID

Sometimes referred to as Study Number.  Pharmaceutical companies also often refer to a Study ID as a Protocol. Identifier given to a single trial by its sponsor.  Each trial may have multiple identifiers.  For example: GlaxoSmithKline’s HPV vaccine study 580299/012 (GSK’s own ID) is also known as HPV-012 (part of the Cervarix programme) and NCT00169494 (registration ID), and may also be referred to by four known publications of the trial.  The IDs may not be immediately reconcilable.
