By contrast, 44% (4/9) of EPO+MLT-treated rats had a normal ventricular volume and only 11% had severe ventriculomegaly, a significant reduction in the proportion with ventriculomegaly compared to vehicle-treated CAM-IVH rats (Wilcoxon rank sum test, p = 0.005). The gene discussed is EPO; the disease is Ventriculomegaly.
