help with Interpreting the results ITS with single interruption

Hi everyone,

I am just wondering if you could give me a hand to make sure what I have done is correct please?
I have run an ITS with single interruption at point 614 (please see below).

1)Could I say the finding suggests that the level of arrivals was at 6333986 (cons) and increasing by 777 (but not significant)?
2)adding in first month of interruption arrivals dropped significantly by -372564 (x614)?
3)but then with significant increase in monthly (_x_t614) trend?
4) finally lincom estimate produced by specifying trend posttrend, that after the interruption, arrival started to pick up?


I hope you can help me :-)
Best wishes
Yeg
