Tailored educational intervention for primary care to improve the management of dementia: the EVIDEM-ED cluster randomized controlled trial

Table 5 Detection rates for new cases of dementia pre/post-intervention period by randomization arm

Period	Rates	Intervention practices	Control practices
Preintervention period	Combined	1.12%	0.63%
	Minimum	0.17%	0%
	Maximum	3.45%	4.4%
Postintervention period	Combined	0.74%	0.50%
	Minimum	0%	0%
	Maximum	1.06%	4.1%

Case detection rates were unaffected by the intervention. The estimated incidence rate ratio (IRR) for the intervention versus the control group from the multilevel Poisson regression modeling was 1.03; the P value was 0.927 with 95% confidence intervals 0.57, 1.86.
