Our Lagrangian is a re-summed version of the effective Lagrangian recently obtained by Demmel, Saueressig and Zanusso~\\cite{Demmel:2015oqa} in the context of gravity as an asymptotically safe theory. It represents a refined Starobinsky model, ${\\cal L}_{\\rm eff}=M_{\\rm P}^2 R/2 + (a/2)R^2/[1+b\\ln(R/\\mu^2)]$, where $R$ is the Ricci scalar, $a$ and $b$ are constants and $\\mu$ is an energy scale.
