Table 1.
The statistics of global drug-target interactions (DTI) network and local DTI network for natural products.
| Data set | ND | NT(NAT) | NDTI | Sparsity (%) |
|---|---|---|---|---|
| Global DTI network | 2,349 | 732 (101) | 17,223 | 1.00 |
| Local DTI network | 224 | 494 (70) | 2408 | 2.17 |
Local DTI network: a specific drug-target network by focusing on FDA-approved or clinically investigational natural products, ND, the number of natural products; NT, the number of targets; NAT, the number of aging-associated targets; NDTI, the number of DTIs; Sparsity, the ratio of NDTI to the number of all possible DTIs.
