WOMAC scores (0–10 scale) as a function of time and treatment group 2 years after the last trial injections. (a) Valid-for-efficacy-population (N=188): patients who did not receive subsequent pharmacological or surgical treatment for OA (ACS: N=76; HA: N=56; saline: N=56). Figure shows mean±SE. *P<0.05 for the comparison ACS vs HA and saline; ‡P>0.05 for the comparison HA vs saline. (b) Intention-to-treat (LOCF) population (N=310): overall cohort with last value carried forward in patients who received subsequent therapies. Figure shows mean±SE. *P<0.05 for the comparison ACS vs HA and saline; ‡P>0.05 for the comparison HA vs saline.
