We shipped eight analytical upgrades to the Patient Similarity Engine last week — hierarchical concept similarity, Love plots, distributional divergence, propensity score matching, UMAP projections, temporal DTW, consensus clustering, and similarity network fusion. The engine is now, arguably, more analytically capable than anything in the OHDSI ecosystem for cohort-level comparison.

But the UI was still the original five-tab layout we built in the first sprint. And no amount of analytical horsepower matters if a researcher opens the page, sees five tabs without context, and doesn't understand the order of operations.

Tonight we replaced it entirely.
