After controlling for covariates, installation of the Bloor Viaduct suicide barrier was associated with a 49% step decrease in bridge-related suicide in the next quarter in Toronto (incidence rate ratio [IRR]\u2009=\u20090.51, 95% CI, 0.30 to 0.86) with no rebound increase in bridge-related suicide during the subsequent 17 years after the original drop (IRR\u2009=\u20090.99, 95% CI, 0.96 to 1.03). There was also no associated change in suicides by other methods after the barrier (IRR\u2009=\u20091.04, 95% CI, 0.90 to 1.20).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Contrary to initial findings, these results indicate an enduring suicide prevention effect of the Bloor Viaduct suicide barrier.
