Estimates for Multilevel Logistic Regression for Attitudes on Gun Safety Counselling as a Function of Individual-Level Variables and Practice
| Model Parameter | Should doctors ask about guns in the home? (n = 750) | Should doctors advise about safe storage? (n = 750) | Should doctors advise parents to remove guns? (n = 729) |

| Single adult in home (reference is ≥2 adults) | 1.04 (0.65, 1.67) | 1.36 (0.78, 2.35) | 1.08 (0.70, 1.66) |
