Abundance of C3, C5, complement factor H and complement-decay accelerating factor (CD55) in never and current smokers. Y-axis shows normalized abundance of protein levels (log2 transformation and normalization to mean 0 and variance 1). Box ranges from the 25th to the 75th percentile and median value is marked with dotted line. p-values from pairwise comparisons are shown over each box plot. Protein abundance data was adjusted for age and the investigator
