highly significantp < 0.006
On comparing the blood indices between the biologics and non-biologics groups of PSA patients, there was a statistically highly significant reduction in red cell distribution width (RDW%) at the biologics group than non-biologics ( p < 0.006), where there was a statistically highly significant increase in Hb (hemoglobin)/RDW ratio and Hb/platelets ratio at the biologics group than non-biologics ( p < 0.005).
