  We present results for fluctuations of the baryon number for QCD at nonzero
temperature and chemical potential. These are extracted from solutions to a
coupled set of truncated Dyson-Schwinger equations for the quark and gluon
propagators of Landau-gauge QCD with $N_f = 2 + 1$ quark flavors, that has been
studied previously. We discuss the changes of fluctuations and ratios thereof
up to fourth order for several temperatures and baryon chemical potential up to
and beyond the critical endpoint. In the context of preliminary STAR data for
the skewness and kurtosis ratios, the results are compatible with the scenario
of a critical endpoint at large chemical potential and slightly offset from the
freeze-out line. We also discuss the caveats involved in this comparison.
