Fig. 5From: Gene variants associated with acne vulgaris presentation and severity: a systematic review and meta-analysisMeta-analysis of CYP SNPs associated with acne presentation and acne severity grades. a Meta-analysis of association of CYP17A1 rs743572 with acne presentation. b Subgroup meta-analysis of association of rs743572 with acne severity among different grades. c Meta-analysis of association of CYP1A1 rs4646903 with acne presentation. 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 rs743572 and C versus T for rs464903Back to article page
