Hi Gloria,

Yes we did make a change in POPLINE. We recently made all abortion
terms stop words. As a federally funded project, we decided this was
best for now. In addition to the terms you’re already using, you
could try using ‘Fertility Control, Postconception’. This is the
broader term to our ‘Abortion’ terms and most records have both in
the keyword fields. Also, adding ‘unwanted w2 pregnancy’ in place
of aborti*. We have a keyword Pregnancy, Unwanted and there are 2517
records with aborti* & unwanted w2 pregnancy

I hope this helps.

Debbie

Hello Debbie:

I left a message on your voice mail today regarding POPLINE, but
didn’t explain the problem I’m encountering, so here is an email
follow-up.

When I ran this strategy on Jan 18, 2008, POPLINE retrieved 1684 refs;
when I re-ran the same strategy today, POPLINE retrieved fewer refs, ie,
1478 refs. Usually, when a search is re-run at a later date, the total
number of references retrieved is more, not less. Has POPLINE
undergone some major change in the past few months that might explain
the decreased retrieval? What can account for this discrepancy?

(strategy removed)

I also tested a second strategy that was developed in Jan 2008 and had
similar results, ie, fewer refs retrieved this time than previous.
Puzzling?!?

Appreciate a prompt response –

Thank you, Gloria
