Serum Prolidase Activity, Oxidant and Antioxidant Status in Nonulcer Dyspepsia and Healthy Volunteers

Table 2

Representation of serum prolidase activity, total antioxidant capacity, total oxidant status, and oxidative stress index in the cases, control-1, and control-2. Data is represented as mean ± standard deviation with their respective units. 𝑃-value of less than 0.05 showed significant changes. Cases have significantly more increased serum prolidase activity, total oxidant status, and oxidative stress index than control-1 and control-2, while total anti-oxidant capacity significantly decreased.
