Happening now! #DaDA PIA session on design and analysis of non-pharmacological interventions in room Harbor C at #AAIC25 ; it's not too late to sneak in and take a seat!

Good morning Toronto! Ready for #AAIC25? It's Professional Interest Area #PIA day today at the Westin Harbour Castle, visit the Design and Data Analytics #DaDA booth for networking (12.30-2.30pm) and our session on design and analysis in trials at Harbour C (3.45-4.45pm)! See you there?

Our new paper in Epidemiology examines how timescale choice—study time vs. age—can influence estimates of exposure effects on memory change. Using data from 10 cohorts, we show how timescale decisions may shape findings and offer guidance for future cognitive aging research. doi.org/10.1097/EDE....
