FIGURE 4.

Mean differences and layered confidence intervals (90 and 97%) for adherence, Modified Oswestry Disability Questionnaire scores (MODQ), and pain (NRS) between groups who required additional (>1) versus no additional (1) boosters in the Post-Booster phase (the six months following the last booster). The darker bars indicate the 90% confidence intervals, and the lighter bars indicate the 97% confidence intervals. MST = motor skill training; SFE = strength and flexibility exercise. Adherence scores range from 0–100% with higher scores indicating better adherence. MODQ scores range from 0–100% with lower scores indicating less disability. Numeric Pain Rating Scale (NRS) values range from 0–10 with lower scores indicating less pain.
