Okay, the following search string resolved my issue -
"Cardiology AND randomized controlled trial[Publication type] AND 2011[PDAT]"
Thank you!

Hello,
When I try to run the following code using the package Easypubmed, I get a null
result -
> batch_pubmed_download(query_7)
NULL
#query_7 <- "Cardiology AND randomizedcontrolledtrial[Filter] AND 2011[PDAT]"
However, the exact same search string yields 668 results on Pubmed.
I am unable to figure out why this is happening. If I use the search string
"Cardiology AND 2011[PDAT]" then it works just fine.
Any help would be greatly appreciated
Thank you!
