From: Assessment of pre-injury health-related quality of life: a systematic review
Pre-injury SF-36 and SF-12 scores by injury type and in comparison to population norm scores. Studies in bold and italics prospectively measured pre-injury HRQL. 1 Adjusted by the age and sex distribution in the study population, based on the weighted health state index by age and sex [13, 14]. 2 Final post-injury measurement: at 3 [27], 6 [43] or maximal 9 months post-injury [18], 1 year post-injury [26, 28, 29, 32, 33, 48], 2 years post-injury [44], or 4–8 years post-injury [46]. Heterogeneity: PCS Chi2 = 12.48, df = 11, (p = 0.33), I2 = 12%; MCS Chi2 = 11.88, df = 11, (p = 0.37), I2 = 7%. MVC: injury due to motor vehicle crash; Ortho: orthopedic injury; TBI: traumatic brain injury
