12 16 An ITS design was applied for estimating the differences in prevalence of methamphetamine use before and after the Meth Project intervention, adjusting for any underlying temporal trend.
Using GLMM regression, scores of the observational checklist at the shift level were compared pre- and post-intervention adjusting for clustering at the hospital level.
Univariate analysis of variance was used to compare differences between the intervention and control group at 3 months post-intervention, adjusting for baseline leakage, age, sex and functional status.
Table 4 presents impact evaluation results comparing intervention and comparison groups at the end of the healthy lifestyle intervention, adjusting for age, sex, diabetic, hypertensive, years of formal schooling, distance to the health center, employed, and lives alone.
On average, systolic blood pressure was reduced 8 mmHg and diastolic blood pressure was reduced 5 mmHg more for the intervention vs. the comparison group from the start to the end of the intervention, adjusting for baseline values and co-variates.
Men in the HIV/STI risk-reduction intervention were less likely to report having receptive anal intercourse during the follow-up period than were their counterparts in the health-promotion intervention, adjusting for baseline consistent condom use and sexual orientation self-identification.
For ITS and RMS we will use either a regression analysis with time trends before and after the intervention, adjusting for autocorrelation and any periodic changes, or the ARIMA (autoregressive integrated moving average) analysis, which is used in time series analyses to understand or predict future trends.
The relative effect, i.e. the effect of the intervention adjusting for the assault incidence in Hamilton, is given by the ratio of the incidence rate ratios in the two study sites, i.e. a 37% relative reduction [(1 0.63) × 100], which equates to 33 assaults prevented per quarter [ 99.0 × 1.02)−67.7].
For each fall outcome, we present the hazard ratios and 95% confidence intervals for the intervention, adjusted for centre.
