Davies test for existence of at least 1 breakpoint: p=5.13032e-295 (e.g. p<0.05 means reject null hypothesis of no breakpoints at 5% significance)

This includes estimates for all the model variables, along with confidence intervals. The Davies test is a hypothesis test for the existence of at least one breakpoint, against the null hypothesis of no breakpoints.

The Davies test is a hypothesis test for the existence of at least one breakpoint, against the null hypothesis of no breakpoints. Following Muggeo ("segmented: An R Package to Fit Regression Models with Broken-Line Relationships" 2008), this uses the Davies test with the Wald statistic on the breakpoint change in gradient.
