Progression of breast arterial calcification in subjects with end-stage renal disease (ESRD) or subjects who underwent kidney transplantation. The boxes represent the interquartile range (IQR), with the intervening line indicating the median. The error bars indicate the maximum and minimum data points within 1.5× the IQR of the first and third quartiles, with symbols indicating outlying points. Data for control subjects and subjects in the lowest chronic kidney disease tertile from Figure 2 are shown for comparison. Significances are determined using the Mann-Whitney U test. eGFR, estimated glomerular filtration rate.
