Table 5 Results from binary logistic regression analysis of playground slide-related injuries. Regression analysis was performed for the indicated outcomes. Outcome 1: injured child being < 3 years old as compared to 3–5 years of age. Outcome 2: Cases identified where the child was on a lap at the time of injury versus not identified as lap-related

From: Playground slide-related injuries in preschool children: increased risk of lower extremity injuries when riding on laps

  1. aOutcome reference = Patients 3–5 years old; Number of cases in model = 5990; Cases not included in the model if they had missing data for one or more of the variables in the model
  2. bOutcome Reference = Injury not identified as occurring when patient was on another person’s lap; Number of cases in model = 5990; Cases not included in the model if they had missing data for one or more of the variables in the model
  3. cWhen the model compared children < 2 years old with children 2–5 years old, the younger age was more likely to be white: aOR, 1.26; 95% CI, 1.08–1.46
  4. dFor the model with age as outcome, only 9 cases were diagnosed with internal organ injury, a number too small to generate aOR and 95% CI
