Additional file 10 of Decreased complement 4 and interleukin-10 as biomarkers in aqueous humour for non-exudative age-related macular degeneration: a case control study

Additional file 10. Summary of biomarker levels of smokers and non-smokers. A comparison between biomarker levels of smokers (n = 11) and non-smokers, including former smokers, (n = 20) was conducted. The second tab shows the subgroup analysis of CCL7, IL-7, and IL-6 between smokers with and without AMD. Parametric data underwent independent-means t-test, presented as arbitrary unit (AU) with mean (M) and standard deviation (SD). Non-parametric data was analysed by Wilcoxon’s rank-sum test, depicted as AU with median (Mdn) with first (Q1) and third (Q3) quartile. * P < .050 represents significance.
