Description
Clinical trial data analysis typically focuses on specific analysis datasets, but the complete journey of individual patients — from screening, enrollment, and first dose, through visit records and adverse events, to last dose and survival status — represents critical time-based data points that reviewers prioritize. This fragmentation of information forces reviewers to switch between multiple reports during in-depth case reviews.
This poster presents an interactive patient timeline visualization system built with R and D3.js. The single-patient view integrates visit records, medication history, adverse events, and survival status into a clear timeline, providing a complete picture of each patient's key trial journey.
The system also supports side-by-side timeline comparisons across patient subgroups, with event type filtering and time range zoom functionality to help identify population-level event patterns and safety signals.
The system takes raw CRF data as input and embeds D3.js interactive capabilities directly into the R workflow, without requiring a separate front-end development environment. This poster will demonstrate visualizations generated from simulated clinical trial data and discuss the practical potential of this approach in clinical data review and safety monitoring settings.
