Table 2 Tests for significance of differences between trial arms in MDRO infection incidence density (MDRO), hand hygiene compliance, and alcohol-based hand rub usage (AHRU) within each year of the study period, respectively (hand hygiene compliance data are from [15] and reprinted with permission)

From: Impact of psychologically tailored hand hygiene interventions on nosocomial infections with multidrug-resistant organisms: results of the cluster-randomized controlled trial PSYGIENE
