article_rating

I'm changing some buttons and icons depending on whether a user has rated/ saved an article or not. I'm using two select queries for that:
rated or not
SELECT given_rating as rating
FROM article_rating
WHERE given_by=? AND article_id=?
saved or not
SELECT saved_by as saved
FROM saved_article
WHERE saved_by=? AND article_id=?
So my question is how can i combine both into one mysql query efficiently??
