Omega-3	65.22 ± 91.93	49 ± 63.11	37 ± 61.29	37.30 ± 76.78	-27.91 ± 128.96	0.554

EPO resistance index (unit/week per Hgb per weight)
Omega-3	14.64 ± 15.12	-	-	15.03 ± 13.40	0.39 ± 7.82	0.086
Placebo	11.17 ± 8.72	-	-	17.26 ± 12.02	6.09 ± 11.89

Notes: All values are mean ± SD. Difference indicates mean difference of month-4 minus baseline. P values were derived using independent t-test or Mann–Whitney U test, comparing mean differences of parameters between two groups (bold faces). P value < 0.05 was considered as statistically significant.
