The comparison of precision and recall of the traditional search method and the NKAS method.

Topic	Num. truly related	Traditional search precision	Traditional search recall	Result Precision	Result Recall
NOAC	21	13.8% (8/58)	38.1% (8/21)	76.9% (20/26)	95.2% (20/21)
Kidney	16	40% (12/30)	75% (12/16)	69.6% (16/23)	100% (16/16)
LAA vs. NOAC	6	50% (4/8)	66.7% (4/6)	75% (6/8)	100% (6/6)
Average		34.6%	59.93%	73.83%	98.4%

Note. Result Precision = (Num. (papers truly related ∩ papers in the search result))/Num. Papers in the search result, and Result Recall = (Num. (Papers Truly related ∩ Papers in the search result))/Num. Truly related. NOAC: novel oral anticoagulant; LAA: left atrial appendage.
