For certain infections, good quality randomized controlled trials are unlikely ever to be done -- hence the importance of large observational studies. This one is potentially practice-changing given the difficulties of high-dose TMP/SMX in some patients.

I don’t know…blood vs respiratory breakdown is interesting. tmp/smx dose (and adrs) arent listed. a lot of colonization gets treated especially when you look back to 2005. Kudos for the effort, but this is a tough question to answer retrospectively.

What’s truly terrifying is that there have been cases of S. maltophilia being resistant to both Levaquin & Bactrim, but more so with Levaquin if I’m not mistaken.

This seems like about as well done a study as could be done with this dataset, but the selection bias with Steno to me is way too strong to do anything retrospectively, especially with no standard infection definition. We need an RCt which, as the authors note, is very hard

As rigorous as you can get with retrospective data. I am extremely jealous at the use of overlap weighting as a statistical method. This weighting mirrors RCTs more closely, and weights cases higher with more clinical equipoise between treatments. Very strong.
