Summary of results from studies examining the effects of laws targeting firearms use (shall issue or right to carry laws, bans on carrying laws, and castle doctrine and stand your ground laws) on homicides and firearm homicides. We present only a single estimate from each study because of space limitations. We selected the estimates from models that, to our consideration, included the most important model specifications. We present the results from studies with comparable results in terms of percent change in firearm deaths (when not provided, we calculated the percent change if there was available information for calculations). Stand your ground laws are presented with castle doctrine laws. The estimate in Grambsch (37) represents the percent annual change in the rate of homicides in the postlaw period compared with the prelaw period. CI, confidence interval.
