Table 4.

Provides estimates of the exponentiated level change, trend change and slope post-estimated change point, as well as corresponding 95% confidence intervals and p-values. The pre- and post-estimated change point slopes are given (scaled) in terms of six month comparisons, thus the inclusion of the $\frac{6}{n}$ term.
