Figure 2.
Box plots of serum concentrations of renal biomarkers in 262 hyperthyroid cats (before and after 131I treatment) and in 206 clinically normal cats. (A) Urea nitrogen; (B) creatinine; and (C) symmetric dimethylarginine. For each serum biomarker, significant differences between the 3 groups of cats are indicated. Boxes represent the interquartile range from the 25th to 75th percentile. The horizontal bar in each box represents the median value. The T‐bars represent the main body of data, which in most instances is equal to the range. Open circles represent outlying data points.
