#RheumJC week!  I hope you all tuned into the online journal club #RheumJC, but if you did not I put up a podcast about the paper we discussed. Yet another epidemiological misadventure into unmeasured confounding and in this case confounding by indication.  Take home... maybe consider not using Tramadol, as you already should have not been doing? 

Article I reference in the podcast: https://emcrit.org/toxhound/tramadont/
