Table 3.

Distribution of binding affinity data points in BindingDB database. DTI data points refer to known drug-target interaction pairs in the database. The variable x represents the count of matching DTI data points, where, for example, 2,661 targets (36.028% of population) have 10 or fewer DTIs.

Number of DTI data points	Number of targets	Population
1000 ≤ x	542	7.338%
100 < x ≤ 1000	1,750	23.693%
10 < x ≤ 100	2,433	32.941%
x ≤ 10	2,661	36.028%
