G I: group I (received NAC supplementation); G II: group II (received none of the supplements); 0 denotes the time of diagnosis of preeclampsia; 1 denotes the first follow up; after 4 weeks of treatment and 2 refers to the second follow up after 6 weeks of treatment. P-value is significant at ≤ 0.05.
