Proportion of deaths preventable by at least one safety device, by selected variable categories, and results of χ2 tests of independence for each category

|---|---|---|
| *For each of the variables (age, type of gun, circumstance), the χ2 tests the null hypothesis that the proportion of preventable firearm related deaths across the appropriate subcategories (that is, the different age, type of gun, and circumstance groupings) is the same. | ||
