“Expanded Embase”  do not exist. There is nothing like “Expanded Embase” .

The correct terms is “Embase”  This clarification was provided by the National Medical Commission (formerly known as the Medical Council of India) in response to an RTI query. 

This revelation has brought relief to many, as the NMC/MCI acknowledged typographical errors in their list of valid indexing services. 

But still if someone insists and asks for non-existent “expanded Embase” indexing then tell him/her to name a journal which is indexed in “Expanded Embase”. And if he can’t do that then you have the answer.
