Professor Ying Ding's student Na Bo has been selected as one of the Health Policy Statistics Section Student Paper Competition winners. She will travel to the 2024 Joint Statistical Meetings in Portland, Oregon this summer to present her work titled "A meta-learner-based framework to analyze treatment heterogeneity in survival outcomes: application to pediatric asthma care under COVID-19 disruption". Their latest paper proposes a meta-learner-based approach to analyze subgroup treatment heterogeneity in survival outcomes, addressing challenges in quantifying heterogeneous treatment effects. They applied this innovative procedure to study asthma exacerbation and identified vulnerable patient subgroups benefiting significantly from a written asthma action plan. Valuable insights for health care policymakers.
