@dr_sajobi @MrGabbs1 @a_predicare Though these talks were methodologically distinct, they all share the same underlying commitment: developing statistical tools that are rigorous, practical, and ultimately serve the patients and clinicians who depend on the evidence we produce.

A proud moment for the @pcma_lab at @SSC_stat 2026!

Our lab had a strong showing at the @SSC_stat Annual Meeting in Hamilton, with four presentations spanning trial methodology, missing data, randomization, and psychometrics.

@dr_sajobi @MrGabbs1 🔹 Tim Biziaev (Statistician) — Minimal Sufficient Balance Randomization and Site-specific Group Size Imbalance in Multicenter Acute Stroke Trials

🔹 @a_predicare (2nd year PhD student) — Detecting Longitudinal Measurement Non-Invariance PROs Using Graded Response Model Trees

[Person-centered Methods and Analytics Lab @pcma_lab]

Congrats to PhD student @a_predicare on the CRAN release of grmtree! The package implements tree-based Graded Response Models for detecting differential item functioning in patient-reported outcomes.

Our lab had a strong presence presenting at #CSEB2025 in Montreal!

Henry Michael (Postdoctoral Associate): Sedative co-medication & frailty in HIV.

Olayinka Arimoro (PhD Student): Response shift in PROMs

Tim Biziaev (Stats. Analyst): Risk prediction models in multivessel CAD

[Oláyinká Ìmísíolúwa Àrímọrọ̀ @a_predicare]

Presented my work on response shift in children with chronic illness at #CSEB2025 in Montreal.

Grateful to Dr. Ferro (@ARCH_Lab) for data access & my supervisors Drs. @dr_sajobi & Lix for mentorship. Loved reconnecting, meeting new colleagues & exploring the city!
