There were 58 patients participating in the study who underwent primary transforaminal lumbar interbody fusion for lumbar spondylolisthesis. The patients were entered into an institutional registry and followed for two years. The researchers ODI had AUC=0.94, suggesting it is an acute discriminator of meaningful treatment.
The most responsive to postoperative improvement was ODI, then NRS-BP and NRS-LP. EQ-5D was most accurate and EQ-5D was most responsive for general health and quality of life, although SF-12, Zung and SF-12 MCS were also accurate discriminators.
