Consecutive patients with CP were randomly assigned to receive placebo or antioxidant supplementation for 6 months, with the main endpoint of the study being pain relief. Secondary endpoints were a need for analgesics and hospitalization. Oxidative stress markers measured were thiobarbituric acid–reactive substances and antioxidant status (ferric-reducing ability of plasma).& n; w4 f0 [5 ~. K

Of 127 patients randomly assigned, 56 were in the placebo group and 71 in the antioxidant group. Compared with the placebo group, the antioxidant group had a significantly greater decrease after 6 months in the number of painful days per month (7.4 ± 6.8 vs 3.2 ± 4 days, respectively; P < .001; 95% confidence interval [CI], 2.07 - 6.23). 2 x/ Z9 j7 [) |/ v) Ptvb now,tvbnow,bttvb % C/ t5 _6 t) B7 }The antioxidant group also had a greater reduction in the number of analgesic tablets taken per month (10.5 ± 11.8 vs 4.4 ± 5.8 tablets, respectively; P < .001; 95% CI, 2.65 - 9.65).
