Dose-response relationship between the duration of cooling and the probability of a full thickness depth of burn. A significant inverse relation is observed between the duration of cooling and the probability of full thickness depth. Relative to burns that failed to receive any first aid cooling, those cooled with running water for lengths of ≥5 minutes had a significantly reduced probability of classification as full thickness, with progressively greater probability reductions in the 5- to 10-minute (OR 0.3; 95% CI 0.1–1.0; P = .04), 11- to 19-minute (OR 0.3; 95% CI 0.1–0.9; P = .03), and ≥20-minute (OR 0.2; 95% CI 0.1–0.4; P < .001) groups.
