Fig. 2From: Evaluation of circulating cell-free DNA in cholestatic liver disease using liver-specific methylation markersLack of correlation between liver-specific cfDNA levels and participant sex. Our study did not identify correlation between sex and liver-specific DNA levels as measured at all 3 genes: IGF2R, ITIH4 and VTN in a Controls, b PBC patients or c PSC patients. cfDNA values expressed as genomic equivalents per ml (Geq/ml). P-values determined using the two-tailed Mann–Whitney test, exact p-values shownBack to article page
