Results of imaging measurement. A Changes in DHI during the follow-up. B Changes in RVG during the follow-up. C Changes in ROM during the follow-up. DHI, Disc Height Index; RVG, the ratio value of the greyscale; ROM, the range of motion; a-d indicate the letter labelling of the time point difference (comparison within the group); if two time points have the same letter, there is no significant difference between the two time points (P > 0.05); otherwise, different letters at 2-time points mean the difference is significant (P ≤ 0.05)
