Table 1 Comparison of mortality rates and associated odds of mortality among different WSES classes of pelvic injuries in the NTDB 2015

From: Accuracy of the WSES classification system for pelvic ring disruptions: an international validation study

Outcomes Minor (N = 37,785) Moderate (N = 3638) Severe (N = 2740) p value
All pelvic injury patients (N = 44,163)
 Mortality rate (N, %) 677 (1.8%) 140 (3.8%) 291 (10.6%) < 0.001*
 Odds of mortality (Baseline) 2.194 (1.823–2.640) 6.513 (5.643–7.517) < 0.001
Outcomes Minor (N = 25,046) Moderate (N = 2074) Severe (N = 3743) p value
Patients with isolated pelvic injuries (N = 30,863)
 Mortality rate (N, %) 355 (1.4%) 64 (3.1%) 305 (8.1%) < 0.001*
 Odds of mortality (Baseline) 2.215 (1.691–2.901) 6.170 (5.273–7.220) < 0.001
