Scatterplot of weighted rates per 100 000 persons; linear regression trend lines are shown for interrupted time series. The slope for pre–Consumer Product Safety Commission (CPSC) involvement was 0.59 (95% CI, 0.48-0.70; P < .001); the slope during the rule was −0.28 (95% CI, −0.39 to −0.17; P = .01); and the slope after the rule was vacated was 0.30 (95% CI, 0.12-0.48; P = .05). The change in slope before involvement vs during the rule was 0.87 emergency department visits per 100 000 persons annually (95% CI, 0.71-1.03; P < .001); the change in slope during the rule vs after it was vacated was −0.58 emergency department visits per 100 000 persons annually (95% CI, −0.68 to −0.47; P = .007).
