JLEQ (A) and JKOM (B) scores in the l-serine (l-Ser) + EPA supplementation group and the placebo group at weeks 0, 4, 8, and 12. Changes in JLEQ score (A) and JKOM score (B) from all study participants at weeks 0, 4, 8, and 12. The JLEQ score is the sum of the JLEQ-II, -III, and -IV scores, and the JKOM score is the sum of the JKOM-II, -III, -IV, and -V scores. Data are expressed as the means ± SDs, n = 60 in each group. ANCOVA using the baseline score as a covariate was performed to detect differences between the 2 groups by each time point. *, **Significantly different from placebo group: *P < 0.05, **P < 0.01. JKOM, Japanese Knee Osteoarthritis Measure; JLEQ, Japan Low Back Pain Evaluation Questionnaire.
