We analyze $N_f=2$ lattice scattering data using unitarized Chiral Perturbation Theory, allowing not only for the extrapolation in mass but also in flavor, $N_f=2\\to N_f=2+1$. The flavor extrapolation requires information from a global fit to $\\pi\\pi$ and $\\pi K$ phase shifts from experiment. While the chiral extrapolation of $N_f=2$ lattice data leads to masses of the $\\rho(770)$ meson far below the experimental one, we find that the missing $","authors_text":"A. Alexandru, B. Hu, M.
