T.S.:Taylor series approach; G.S.: generating series approach; S.T.: Similarity transformation approach; D.T.: Direct test; D.A.: differential algebra based approach; I.F.T.: method based on the implicit function theorem; I.D.R.N.: identifiability analysis based on the reaction network theory; SGI: structural global identifiable, SLI: (at least) structural local identifiable, SNI: structural non-identifiable, NA: not applicable, NC: not conclusive and NR: no results were reported due to computational errors or requirements.
