List of source documents that the annotators selected for each piece of information labeled as not sourced from inpatient records.

The numbers indicate the percentage of external documents in each section.Low subj, High subj, Pre-hosp, and In-hosp in the table show the distribution of assumed external sources for segments classified as unsourced. Because it has a multi-label structure, each segment may have multiple source labels, and the percentile is calculated against the total number of assigned labels.
