National numbers of seclusion/involuntary medication before and after the start of a nationwide program. Total number of seclusions and involuntary medications in the Netherlands per quarter, before and after the start of a nationwide program in 2006 to reduce the use of seclusion, both in absolute numbers and using a Poisson regression line. The slope of the regression line of the quarterly numbers of seclusions before 2006 differs significantly from that after 2006 (p < 0.001). The slopes of the regression line of the quarterly numbers of involuntary medications before and after 2006 do not differ significantly from one another.
