This is just clipped and not to be taken as gospel despite being peer reviewed. However, for the most part it's more than what is usually trotted out by the pro registry crowd.
ARIMA analysis also failed tofind gradual permanent effects that might have occurred after 1998 with thereplacement of the FAC by the PAL/POL and the implementation of the long-gun registry (firearm homicide: ARIMA[1,1,0] 86.21% increase, B = 0.27,p = .94; long gun: ARIMA[1,1,0] 77.61% reduction, B = –0.65, p = .60).
To adjust for the effects of previous legislation on subsequent legislation, amodel combining all legislation was produced (Figure 2, SupplementaryFigures B and C). A trend of increasing firearms homicide was noted post C-68(year 1998: Btrend = +0.06, p = .05, % change = +14.8%) but no significant stepeffects were discovered suggesting the step noted in 1998 is not significant.Late effects of C-68 coming into effect in 2001, such as the PAL/POL, was also

Spousal homicide by firearm was also examined using interrupted regres-sion and ARIMA. No associations were found after C-17 was passed and upto 4 years afterward (Figure 2; Table 2; Spousal Firearm Homicide:ARIMA[0,1,1] 2.1% reduction, B = –.009, p = .75). C-68 also produced noassociation either immediately after passage or after the implementation ofthe PAL/POL (2001) or long-gun registry (2003; Figure 2; Table 2; SpousalFirearm Homicide: ARIMA[0,1,1], 1996, 0.9% reduction, B = –0.004, p =.89; 2001, 2.5% reduction, B = –0.01, p = .72; 2003, 2.8% increase, B = 0.01,p = .69; spousal long-gun homicide, ARIMA[2,1,0], 1996, 1.1% reduction,B = –0.005, p = .82; 2003, 1.9% increase, B = 0.01, p = .74).
