Poster Session for STAT 450

Wednesday, April 2, 2025 - 09:00 to 10:15
STAT 450 Students
Poster Session
ESB Atrium - East Corridor (PME Gallery)

STAT 450 students have worked collaboratively on real case studies brought by researchers from other disciplines. Supervised by the teaching team, STAT 450 students performed various statistical analyses to address their “client’s” questions. Results from seven exciting projects are presented in this poster session. 

Poster 1: Investigating Sources of Variability in Mechanical Parameters and Spinal Cord Injury Severity in Pig Models: An In-Vivo Study to Achieve Consistent Injuries Across Different Animals 

Collaborator: Amir Borjali (School of Biomedical Engineering, UBC) 

STAT 450 Team:  Ece Celik, Alex Grinius, Jessie Liang, Henry Zhang 

The lab we are working with uses porcine (pig) models to investigate the relationship between the severity of spinal cord injuries and their inciting mechanical factors (force, velocity, displacement) through weight-drop impactor experiments. We investigate how the anatomical characteristics of a spine affect measurement variation, and the effect of adjusting pre-impact parameters (eg. drop-height) on those mechanical measurements. 

Poster 2: A retrospective review of PreserFlo® Micro-Shunt utilizing a donor patch graft in glaucoma surgery 

Collaborator: Kevin Makasoff (UBC Medicine) 

STAT 450 Team: Heidi Lantz, Bill Makwae, Jinghan Xu  

We analyze patient data to assess whether incorporating a donor patch graft in PreserFlo MicroShunt surgery enhances glaucoma treatment. By examining intraocular pressure, the need for secondary interventions, and overall ocular health, we aim to provide an understanding of the patch's impact on glaucoma patients. 

Poster 3: Classifying Mantle Compositions using Geochemical Data from Hawaiian Lavas 

Collaborator: Elly Thistlethwaite (Earth, Ocean and Atmospheric Sciences, UBC) 

STAT 450 Team: Kratika Rathi, Moira Renata, Utsav Singh, Alex Tang 

This study explores whether trace element data can reproduce the established classification of Hawaiian volcanoes into six geochemical subgroups, originally identified using isotope ratio data. Using statistical and machine learning methods such as LASSO and Random Forests, we evaluate the predictive accuracy of these models in classifying the geochemical groups and evaluate their statistical significance. 

Poster 4: Impact of onsite endocrinologist-led multidisciplinary teams on outcome of diabetes 

Collaborators: Judy Ban and Rita Jin (UBC Medicine)  

STAT 450 Team: Wanqing Hu, Ruhani Kaur, Jingyuan Liu, Anne Nguyen 

The multidisciplinary team (MDT) framework integrates an endocrinologist, pharmacist, and nurse into initial patient consultations, providing a more collaborative approach to diabetes care. This study examines whether the MDT framework is associated with improved diabetes-related outcomes, such as hemoglobin A1C, low-density lipoprotein, and glomerular filtration rate, as well as patient engagement at Diabetes Education Centres (DEC), compared to the conventional “one-size-fits-all” diabetes care protocol in BC. 

Poster 5: Action-Tendency Retraining in Severe Psychiatric Inpatients with Stimulant Use Disorders: Effects on Stimulant Craving, Treatment Outcome and Implicit Drug-related Memory Associations  

Collaborator: Stefanie Todesco (Neuroscience, Institute of Mental Health, UBC) 

STAT 450 Team:  Quanwei Chen, Yanxin Liang, Xiaolei Lin, Jessie Zhao 

Action-Tendency Retraining (ATR) is a behavioral intervention designed to reduce approach biases toward stimulant-related cues of stimulant disorder psychiatric inpatients. This study evaluates ATR’s impact on stimulant craving, implicit memory associations, and relapse risk in psychiatric inpatients. 

Poster 6: Career Development in Recovery from Problematic Substance Use: A Randomized Controlled Trial of a Hope-Action Theory Group Program 

Collaborator: Teresa Maynes (Counselling Psychology, UBC) 

STAT 450 Team: Sadia Khan Durani, Qingfeng Shen, Anyna Wang, Zhaolan Wang 

This project examines whether the Hope Action Theory (HAT) career counseling program leads to greater improvements in work-related behaviours and cognitions compared to the Standard Employment Skills (SES) program for individuals recovering from problematic substance use (PSU).

Poster 7: The Effect of Estrogen and Progesterone on the way we Breathe during Exercise in Hypoxia and Normoxia  

Collaborator: Sierra Arn (Kinesiology, UBC) 

STAT 450 Team: Thomas Farrell, Licy Li, Vicky Lin, Lily Xie  

Using data collected from premenopausal and postmenopausal females, we examined how hormone levels, oxygen condition, and other factors influence women’s breathing during exercise. Through mixed-effects linear regression, we found a hypoxic environment led to significantly higher ventilation, but we found no statistically significant differences in ventilation associated with hormone levels.
