Correlations of change in FABP4 level with parameters. a–c Fatty acid-binding protein 4 (FABP4) level at baseline (a), change in waist circumference (b) and change in creatinine level (c) were plotted against change in FABP4 level in each subject (n = 307). Closed circles and solid regression line: anagliptin treatment group (n = 148), open circles and broken regression line: sitagliptin treatment group (n = 159)
