The meta-analysis of COL5A1 expression levels between cancerous tissues and non-cancerous tissues in BC based on the GEO database. (A) The forest plot of COL5A1 expression levels based on 19 microarrays. (B) Sensitivity analysis. Red circles represent the chips from sources of heterogeneity. (C) The forest plot of GEO meta-analysis after eliminating three chips considered to be sources of heterogeneity. (D) The publication bias. Red dots represent each GEO chip and the dotted line represents the regression line. SMD, standard mean difference; CI, confidence interval; COL5A1, collagen type V α-1 chain; GEO, Gene Expression Omnibus.
