Details

When year is specified, the argument pmid should be NULL. Then, get.dataset.index returns all systematic reviews found in the database under this year.

Value

get.dataset.index returns a vector (when pmid is scalar) or a data-frame (when pmid is a vector) with the following characteristics (column names):
