Association between plasma betatrophin levels and the presence of PAD
The plasma betatrophin levels were significantly higher in PAD than in PAD(-). The central line represents the median, and the box represents the 25th to 75th percentiles. The whiskers represent the lowest and highest value in the 25th percentile minus 1.5 interquartile range (IQR) and 75th percentile plus 1.5 IQR, respectively.
