(A) Patients enrolled into the National Spinal Cord Injury Database (NSCID) within 1 day after spinal cord injury (SCI) were assigned to long-term follow-up. Datasets from the NSCID collected between 1995 and 2005 comprise data on pneumonia or postoperative wound infection (Pn/Wi) and motor items of the Functional Independence Measure (FIM) long-term outcome. Thus, those datasets were screened for eligibility. The data for statistical analysis were selected stepwise with respect to quality aspects of the particular assessment tools, possible confounding factors, and the availability of key baseline data. The linear mixed regression models were performed as a complete case analysis and—in order to control for attrition bias—after multiple imputation. *Total numbers may differ from subgroup numbers because some items applied multiple times. (B) Assessment points following SCI are indicated representing medians and interquartile range. AIS = American Spinal Cord Injury Association impairment scale; ISNCSCI = International Standards for Neurologic Classification of Spinal Cord Injury.
