Fig. 7From: Exosomal microRNAs are novel circulating biomarkers in cigarette, waterpipe smokers, E-cigarette users and dual smokersVenn diagram showing the overlap of differentially expressed microRNAs identified from comparing four groups: non-smokers vs. cigarette smokers, non-smokers vs. waterpie smokers, non-smokers vs. E-cig users and non-smokers vs. dual smokers. a The overlap of all differentially expressed microRNAs, b The overlap of up-regulated differentially up-regulated expressed microRNAs, and c The overlap of differentially down-regulated differentially expressed microRNAsBack to article page
