In the article by Wang et al (Downregulation of renal CYP-derived eicosanoid synthesis in rats with diet-induced hypertension), which appeared in the October 2003 issue (Hypertension. 2003;42:594–599), there was an error in Figure 4B. The measurements in the Y axis should have been 0 to 70 pmol/mg/min, instead of 0 to 700, as published. Figure 4B is shown correctly here. The author regrets this error.
