| aP values were calculated based on Mann-Whitney test (significance at P<0.05). bR value was calculated from the arithmetic mean values of each group. R=(B-A)/A. R
with a positive value indicates a relatively higher concentration present in cancer group while a negative value means a relatively lower concentration as compared to the
healthy controls. |
