Table 3 Multivariate analysis, binomial logistic regression results, independent predictors of complications

From: Prolonged resuscitation of metabolic acidosis after trauma is associated with more complications

Independent variable Regression coefficient (B) Wald statistic Significance Odds ratio 95 % CI for odds ratio

  1. A 2.7-h increase in time to resuscitation had equivalent odds for sustaining a complication as a 1-unit increase on the ISS
  2. ISS Injury Severity Score
  3. p < 0.05
  4. aA negative value for gender suggests females suffer fewer complications than males
  5. bA negative value for femur fracture suggests that patients with a femur fracture suffer fewer complications than those without
