Fig. 3From: Expression and 7-day time course of circulating microRNAs in septic patients treated with nephrotoxic antibiotic agentsPrincipal component analysis of the relationship between miRNAs and biochemical variables on study day 1. Principal component analysis biplot shows log 2–transformed label-free quantification of the concentrations of variables and the difference between miRNA expression and renal injury or inflammation markers on day 1 in all patients, regardless of subsequent treatment. No relationship was identified between miRNAs and biochemical variablesBack to article page
