Values are presented as number (%).

NASS, North America Spine Society; LBP, low back pain; ND, not done given the total cell count of the 2 groups analyzed.

^*p < 0.05, statistically significant difference.

^†Fisher exact test, comparing the group who had a NASS-concordant approach with those who had a NASS-discordant approach.

^‡Fisher-exact test was not performed.
