EHRStruct (Synthea) - Subtraction: leaderboard
EHRStruct (Yang, Zhao and Shen, 2025) tests language models on structured electronic health record tables. This board is its D-R4 task on synthetic Synthea records: 100 zero-shot questions, each asking the model to subtract one numeric field of a patient from another (for example income minus healthcare expenses), rounded to two decimals from a table given as plain text. Exact-answer accuracy in percent, higher is better; models that produced no valid output are left out.
Metric: Accuracy (%; D-R4: 100 zero-shot questions on synthetic Synthea patient tables given as plain text, where each item asks to subtract one numeric field of a patient from another (for example income minus healthcare expenses), rounded to two decimals; an answer counts when it matches the reference exactly; the paper's check mark, a perfect score, reads 100, and its cross, no valid output, reads as missing). Source: arxiv.org. Saturation forecast: Estimated already saturated. 16 models tracked.
