Slope data for trends in alcohol status recording by intervention site status and intervention
| Variable | Alcohol status recorded (average per month), % | Pre-intervention slope (95% CI) | Post-intervention slope (95% CI) | Comparison of slopes, pre/post (95% CI) | |
|---|---|---|---|---|---|
| Pre-intervention, 21 months | Post-intervention, 10 months | ||||
| Non-intervention practicesa | 55.2 | 56.4 | 1.002 (0.999 to 1.004) | 1.000 (0.998 to 1.002) | 0.998 (0.996 to 1.001) |

a
The number of non-intervention practices varied per month, with an average of 344 and a range of 194–382 practices per month.
b
One practice was outside the PHN catchment area so only five practices are included in the quantitative data. PHN = primary health network.
