Fig. 1From: Fibroblast growth factor 21 is associated with widening QRS complex and prolonged corrected QT interval in patients with stable anginaPatients with wide QRS complex had significantly higher fibroblast growth factor 21 (FGF21) compared to patients with normal QRS complex (A). Patients with prolonged QTc interval had significantly higher FGF21 compared to patients with normal QTc interval (B). The bottom of the box plots indicates the 25th percentile and the top indicates the 75th percentile. The middle line of the box indicates the median. The lower and upper ends of the whiskers indicate the minimum and maximum observations below the upper fence (1.5 interquartile range above the 75th percentile), respectivelyBack to article page
