Subgroup analysis of patients with pre-operative malalignment showed a trend towards greater improvement in the NDI at 12 months with a C2 UIV ( P = .054).
A subgroup analysis of those with malignment showed that the number of patients reaching MCID for the NDI was 20% higher at 12 and 24 months in the C2 UIV but this did not reach statistical significance ( P = .124 and P = .083) ( Table 4 ).
