1  From a fit to the ${{\mathit e}^{+}}{{\mathit e}^{-}}$ cross section between 2.00 and 3.08 GeV with a sum of Breit-Wigner amplitude and a non-resonant contribution.
2  By a simultaneous fit of the ${{\mathit K}_{{{2}}}^{*}{(1430)}^{+}}{{\mathit K}^{-}}$ and ${{\mathit K}^{*}{(892)}^{+}}{{\mathit K}^{-}}$ intermediate channels in a partial-wave analysis, assuming the same structure, modelled with a coherent sum of a nonresonant component and a resonant component by a Breit-Wigner function.
3  From a fit to the cross section between 2.00 and 3.08 GeV with a coherent sum of Breit-Wigner amplitudes, including contributions from ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}/{{\mathit \phi}{(1680)}}$.
4  From a fit to the cross section below 3.5 GeV measured by BaBar and BESIII with a coherent sum of two modified Breit-Wigner amplitudes (${{\mathit \phi}{(1680)}}$ and ${{\mathit \phi}{(2170)}}$) and a nonresonant term.
5  From a fit using a coherent sum of a phase-space modified Breit-Wigner function and a phase-space term.
6  By a simultaneous fit of the intermediate channels in a partial-wave analysis, assuming the same structure, modelled with a coherent sum of a nonresonant component and a resonant component by a Breit-Wigner function.
7  From a VDM fit to ZHU 2023 ${{\mathit \eta}}{{\mathit \phi}}{{\mathit \gamma}}$ data with two resonances, ${{\mathit \phi}{(1680)}}$, ${{\mathit \phi}{(2170)}}$, and a third resonance with mass $1850.7$ $\pm5.3$ MeV and width $25$ $\pm35$ MeV of 1.7 $\sigma $ statistical evidence.
8  From the analysis of the combined measurements of ${\mathit \sigma (}$ ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \eta}}{{\mathit \phi}}{)}$ from BaBar, Belle, BESIII, CMD3. The statistical significance for ${{\mathit \phi}{(2170)}}$ is 7.2 $\sigma $.
9  From a fit to the cross section between 2.00 and 3.08 GeV with a sum of Breit-Wigner amplitude and a nonresonant contribution. The observed structure can be also due to ${{\mathit \rho}{(2150)}}$.
10  The observed structure can be due to both the ${{\mathit \phi}{(2170)}}$ and ${{\mathit \rho}{(2150)}}$.
11  Fit includes interference with the ${{\mathit \phi}{(1680)}}$.
12  From the ${{\mathit \phi}}{{\mathit f}_{{{0}}}{(980)}}$ component.
13  From a fit with two incoherent Breit-Wigners.
14  From the ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit f}_{{{0}}}{(980)}}$ component.
15  Superseded by LEES 2012F.
