We recently covered an SMFM abstract that was presented at the annual Pregnancy Meeting held in early February 2026. The authors were from my Alma Mater, UT Southwestern/Parkland Hospital. This was a well-done study comparing 162 milligrams aspirin to 81 milligrams of aspirin. The results were very encouraging! However, aspirin definitely has an awkward acumen. It would be wonderful if ALL the data just leaned in the same direction... but it doesn’t! Enter our podcast family member, and my friend Alex. Alex sent me an incredible and insightful message which was a rebuttal to my Southwestern colleagues’ findings. In this episode you'll hear Alex's rebuttal and clinical conundrum, and we will explain why these two seemingly paradoxical findings makes sense. Listen in for details.
