Fig. 2From: Decreased IL-8 levels in CSF and serum of AD patients and negative correlation of MMSE and IL-1βCytokine levels in serum of AD patients and age-matched controls. Box plots comparing Serum IL-1β, IL-8 and TNF-α levels between AD patients and age-matched controls. a IL-1β levels were unchanged (p = 0.81). b IL-8 levels were significantly reduced in AD patients (p = 0.02). c TNF-α showed a slight reduction in AD patients but the observed effect was not significant (p = 0.05). Dark horizontal lines represent the mean, with the box representing the 25th and 75th percentiles of the observed data, the whiskers representing the 5th and 95th percentiles, and outliers represented by dots. P values were calculated using the Mann-Whitney Rank sum testBack to article page
