“…There was a statistical trend, suggesting that a closed head injury was also an independent predictor of survival (P = .07), which would not be unexpected, but did not reach significance because of the small number of patients we had with this type of injury. Many others have used the JTTR for research [32][33][34] with inhospital mortality 10,13,24,32,33,35 as the primary outcome; however, the JTTR has significant limitations, as detailed by others. 36 The JTTR was designed to capture demographic and outcome data for process improvement, such as the development of clinical practice guidelines.…”
