  We summarize our results on baryon number fluctuations at nonzero temperature
and chemical potential. They are obtained from solutions of a coupled set of
Dyson-Schwinger equations for the quark and gluon propagators of QCD in Landau
gauge with $N_f=2+1$ quark flavors. In comparison with preliminary STAR data,
our results are compatible with a critical endpoint at large chemical potential
and a freeze-out line that bends below it.
