| CZ14 | AGN | 85 (31.4%) | 49 (18.0%) |
| Non-AGN | 73 (26.9%) | 64 (23.6%) | |
| AS18 (R75) | AGN | 55 (16.7%) | 2 (0.6%) |
| Non-AGN | 128 (38.9%) | 144 (43.8%) | |

| Non-AGN | 151 (45.9%) | 145 (44.1%) | |
Notes. The comparison is performed on an optically selected sample of 329 AGN galaxies. Columns represent our classification results while rows are the classification obtained by the other diagnostics. The R75 and R90 refer to the two available schemes in the work of Assef et al. (2018) that give 75 and 90% reliability for AGN selection, respectively. References: JR11, Jarrett et al. (2011); MT12, Mateos et al. (2012); CZ14, Coziol et al. (2014); AS18, Assef et al. (2018).
