Key Finding
Analysis modules detected multiple biosignal shifts after ruxolitinib initiation, but the 8-day post-intervention window remains too short for strong causal claims. 0/0 CausalImpact streams reach raw p<0.05; 0/0 survive FDR correction. Separate UKF comparisons: Cardiac Reserve shift p=0.040, Sleep Quality shift p<0.001.
