From: Proteomics approach identifies aqueous humor biomarkers in retinal diseases
a Boxplot of median NPX values across diseases. b Scatterplot representing the relationship between age (x-axis) and median NPX (y-axis). Each point on the plot corresponds to an individual sample. The blue line indicates the linear trend. c Boxplot of total protein measured in aqueous samples across diseases. d Scatterplot representing the relationship between median NPX (x-axis) and total protein (y-axis). The blue line indicates the linear trend. Boxplots indicate median and interquartile ranges (IQR) and the whiskers extend from the box to the smallest and largest values within 1.5 times the IQR from the quartiles. N  = 30 non-AMD controls, N = 30 iAMD samples, and N = 28 GA samples. P-values calculated using the Student t-test. GA geographic atrophy, iAMD intermediate age-related macular degeneration.
