The Q test (Tukey HSD [honestly significant difference]/Kramer) and post hoc ANOVA (analysis of variance) test showed a highly significant improvement in the control score at 6 months compared with the initial evaluation ( P = 1.29E-13) and between the initial assessment with the 12 months later ( P = 2, 65E-11).
Patients with central stenosis were also at a greater risk for dural tear compared with those without central stenosis; however, this was not quite statistically significant (OR = 3.28, P = .097).
Of the LLIF parameters measured, factors associated with at least a borderline significance ( P < .2) in a univariate regression analysis were included in a multivariate regression analysis.
A strong trend toward higher revision rates was seen in decompression alone, consistent with historical literature; however, our results may be influenced by the progression of decompression techniques over the study period.
However, ADSCs only showed a trend toward higher fusion mass volume and rates of fusion compared with BMSCs.
The rate of reoperation was highest in the Obese II group at 8.07%, but this did not reach statistical significance.
