of the traversable wormhole, the behaviors of different energy conditions in the DGP braneworld scenario will tend to be 0, which is completely consistent with those in the standard cosmological scenario ($p+\rho=0$). In fact, it is substantially reasonable because the energy density $\rho$ of the material threading the wormhole will approach 0 very fast with increasing radius ($\rho=-\frac{1}{\omega_{eff}(z) r^2}$).

Discussion and conclusions
==========================

In this work, for the first time, we investigated the characteristics and properties of a traversable wormhole constrained by the current astrophysical observations in the framework of MOG. As a concrete case, we studied traversable wormhole space–time configurations in the DGP braneworld scenario, which are supported by the effects of the gravity leakage of extra dimensions. As in our previous works [@39; @40; @41; @42], we first constrain the DGP braneworld scenario by using various data sets, including SNe Ia, OHD, Planck, and a single data point from the single event GW150914. We find that the two different joint constraints, i.e., SNe Ia+OHD+GW and SNe Ia+OHD+Planck+GW, share a substantially high degeneracy and that the wormhole space–time structure will open in terms of the $2\sigma$ confidence level when we take the joint constraints SNe Ia+OHD+Planck+GW and $z<0.2874$ (see
