Fig. 3From: Gene variants associated with acne vulgaris presentation and severity: a systematic review and meta-analysisMeta-analysis of IL SNPs associated with acne presentation. a IL1A rs1800587. b IL6 rs1800796. c IL8 rs4073. Only gene variants that were investigated in at least two other previous studies were included in the meta-analysis. Analysis was performed under allele model (minor allele vs. major allele), i.e. T versus. C for rs1800587, C versus. G for rs1800796 and A versus T for rs4073Back to article page
