EPO and VEGF Absolute Values and Change From Baseline by Visit and Sample Time (ITT Population; Post-Hoc Analyses). Each boxplot displays the distribution of the parameter indicated on the Y-axis label. The bottom and top edges of the box indicate the intra-quartile range (IQR); that is the range of values between the 25th and 75th percentiles. The line inside the box indicates the median value. The whiskers are drawn from the box to the most extreme point that is less than or equal to 1.5 times the IQR. The dots are outliers that are more extreme than the upper and lower fences (±1.5 IQR). EPO, erythropoietin; ITT, intention-to-treat; VEGF, vascular endothelial growth factor
