Fig. 1From: Proteomics analysis of plasma protein changes in patent ductus arteriosus patientsVolcano plot of proteins detected by iTRAQ among PDA patients and controls. The green dot represents decreased protein levels (p < 0.05 and fold-change< 0.5), and the red dot represents increased protein levels (p < 0.05 and fold-change> 2.0)Back to article page
