The values were expressed as Mean ± SEM of Healthy subjects (n = 30), Normocytic normochromic Anemia (n = 30), Alzheimer's disease (n = 10), CKD with cognitive dysfunction (n = 30) and CKD without cognitive dysfunction (n = 30). Letters a, b, c and d denote the statistical significance of the data at the level of P < 0.05. (a) denote comparison of control Vs. other groups; (b) denote comparison of normocytic normochromic anemia Vs. Alzheimer's disease (AD), CKD with and without cognitive dysfunction groups; (c) denote comparison of AD Vs. CKD with and without cognitive dysfunction groups; (d) denote comparison between CKD with and without cognitive dysfunction groups.
