Carragee et al. | 2000 | Of the 42 symptomatic patients, 25 had HIZ: 1 patient had three HIZ discs; 6 patients had two HIZ discs; and 18 patients had one HIZ disc. The asymptomatic group had 13 HIZ discs in 13 of the 54 patients (24%). No reliably associated with HIZ of LBP. |
Hancock et al. | 2012 | No significant differences in rates of MRI findings between controls with no and 1–2 past episodes of LBP. |
Takatalo et al. | 2012 | HIZ occurred in similar frequencies in all clusters of LBP and back-related functional limitations. However, there is no significant association between HIZ lesions and LBP. |
Wang et al. | 2012 | The LBP rate of HIZ patients was significantly higher than that of patients who exhibited no HIZ (57.5 vs. 47.8%, p < 0.05). There was no evidence for a correlation between LBP and spatial distribution of HIZ in disc (p > 0.05). |
Liu et al. | 2014 | The mean signal of HIZ in symptomatic subjects was significantly brighter than in asymptomatic subjects (57.5 ± 14.0% vs. 45.6 ± 7.22%, p < 0.05). There was no statistical difference of area of disc and HIZ between the two groups. MRI index was found to be higher in symptomatic subjects comparing with asymptomatic subjects (3.94 ± 1.71 vs. 3.06 ± 1.50, p < 0.05). |
Yang et al. | 2015 | LBP incidences were compared between the groups of HIZ (+) and HIZ (−). The data demonstrated that 60.7% (17/28 patients) of patients in HIZ (+) group were with LBP, while 20.7% (6/29 patients) of patients in HIZ (−) group were with LBP (p < 0.05) |
