Characteristics of XXXX that predict @entity358 : A secondary analysis of data from a randomized trial.

BACKGROUND: Although @entity130 is common, little is known about which factors lead to poor functional outcomes. We sought to determine which characteristics of @entity764 predict @entity358 or health-related quality of life. METHODS: We conducted a secondary analysis of data from a randomized trial involving @entity1 with @entity764 at a Level I @entity130 center between December 2007 and July 2012. We evaluated the overall severity of the @entity764 -characterized primarily by the number of @entity174 -and rib @entity174 location (upper, middle, and lower; anterior, lateral, and posterior) as predictors of @entity1 -reported outcomes 60 days after injury: @entity1353 burden (0-40), Modified Medical Research Council Dyspnea Scale (MMRC) (0-4), St. George's Respiratory Questionnaire (SGRQ), and normalized Medical Outcomes Study Short-Form 36 (SF-36) scores. RESULTS: Of 189 evaluable subjects, the mean (SD) number of @entity174 was 5 (4). The number of @entity174 was not associated with @entity1353 burden, MMRC, or SGRQ scores. After adjustment for confounders, each additional fractured rib was associated with worse SF-36 Physical Functioning and Bodily @entity158 scores (-0.6 units [95% confidence interval (CI), -1.1 to 0.0] and -0.8 units [95% CI, -1.3 to -0.2], respectively). @entity174 were associated with worse @entity1353 burden (3.4 units; 95% CI, 1.0-5.9), MMRC score (0.4 units; 95% CI, 0.0-0.8), and SF-36 Physical Functioning, Role-Physical, Role-Emotional, and Physical Component Summary scores (-4 units [95% CI, -8 to 0], -5 units [95% CI, -8 to -1], -4 units [95% CI, -8 to 0], and -4 units [95% CI, -7 to -1], respectively). CONCLUSION: The overall anatomic severity of @entity764 does not predict @entity1109 60 days after injury, but it does predict increased @entity1 perceptions of @entity158 and physical function limitations. @entity174 predict both persistent respiratory symptoms and perception of decreased overall health. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.
