Table 4 Logistic regression analysis of the use of intramedullary nail (IMN) versus sliding hip screw (SHS) with or without trochanteric support plate (TSP) on patient characteristics, fracture classification, and hospital characteristics. The analysis was performed on 15,655 (10,600 SHS and 5055 IMN) cases with complete data
