Performance of the text mining algorithm for diagnosis

Outcome	n
Complete match	71
Algorithm reported overlapping diagnosis of LLD/CLE in context of SLE, whereas immunologist did not report overlap	9
Algorithm missed an overlapping diagnosis	4 a
Algorithm assigned an extra overlapping diagnosis	4 a
Diagnosis wrongly assigned by algorithm	5
Diagnosis missed by algorithm	8

Comparison of 100 randomly selected patients: diagnosis assessed by text mining algorithm compared to assessment of a clinical immunologist.

Abbreviations: CLE, cutaneous lupus erythematosus; LLD, lupus‐like disease; SLE, systemic lupus erythematosus.

^aIn one case, the text mining algorithm missed one overlapping diagnosis and misdiagnosed another overlapping diagnosis. This case is represented in both rows.
