Adverse events

 Intercept

3.08 (2.93, 3.24)

  

 Pre-intervention trend

−0.17 (− 0.49, 0.17)

0.29

There is a trend (non-significant) for reducing events but the paucity of them occurring (in relation to raw numbers) makes it difficult to draw concrete conclusions.

 Change in slope (implementation period vs. pre-intervention period)

0.02 (−0.30, 0.33)

0.98

The trend does not appear to change but the confidence limits around this are large.

 Immediate change in level (implementation period vs. pre-intervention period)

0.29 (−1.74, 2.32)

0.78
