Agreement Matrix for Mention and Use.

Metric	Mention (%)	Use (%)
Concurrence Rate (LLM vs Human Majority)	76.0	56.0
Plausibility Rate (LLM vs Minimum 1 Rater)	80.0	82.0
Pairwise Agreement - Raters 1 and 2	98.0	68.0
Pairwise Agreement - Raters 1 and 3	94.0	74.0
Pairwise Agreement - Raters 2 and 3	92.0	74.0
Overall Human Pairwise Agreement	94.7	72.0

Note: Concurrence rate is the proportion of publication-dataset pairs in which the LLM classification matched the human majority vote (yes or no for mention; yes or no for use). Plausibility rate is defined as agreement with at least one of the three reviewers.
