Article summary:

1. Clinic letters in electronic health records (EHRs) contain valuable information for clinical research, but extracting critical information for analysis is time-consuming and error-prone due to the free-text format and different writing styles of clinicians.

2. Visual analytics (VA) and visualization have great potential to support clinical decision making and inform further research, but usability is an obstacle to further analysis of EHR data.

3. LetterVis is an interactive letter-space visualization tool that leverages natural language processing (NLP) techniques to support the exploration of unstructured clinical text in a structured manner, with customized visual designs to identify and verify patterns and outliers in a cohort of patients, dynamic analysis and comparison of antiepileptic drug (AED) co-prescriptions through multiple coordinated visual layouts, and replicable case studies demonstrating its ability to support hypothesis verification.
