XI	Total number of unique molecules	1155

The number of SCRAs shared between the three databases is also presented, as follows: I= total number of molecules included in the NPS. Finder database; II= total number of molecules included in the UNODC list; III= total number of molecules included in the EMCDDA list; IV= number of molecules included in all three lists; V= number of molecules included in both NPS.Finder and UNODC lists, but not in the EMCDDA one; VI= number of molecules included in the NPS.Finder and EMCDDA lists, but not in UNODC one; V= number of molecules included in both UNODC and EMCDDA lists, but not in the NPS.Finder one; VIII = number of molecules included only in the NPS.Finder list, IX = number of molecules included only in the UNODC list; X = number of molecules included only in the EMCDDA list; XI: total number of unique SC molecules identified.
