I'm new to Entrez searching, and I've been looking at the following article: https://dataguide.nlm.nih.gov/classes/intro/samplecode.html

Here is what I have:

esearch -db pubmed -query "(diabetes AND pregnancy AND NIH)" -datetype PDAT -mindate 2015 | \
  efetch -format xml | \
  xtract -pattern Grant -element Agency | \
  sort-uniq-count-rank | \
  head -n 2

But I don't think this is correct. Is there a way to compare only the Agency names with "NIH?"
