Leptin and adiponectin levels correlated with body mas index in SSc patients (<i>r</i> = 0.495, <i>p</i> = 0.000398 and <i>r</i> = -0.306; <i>p</i> = 0.0342) in contrast to healthy controls (<i>p</i> = 0.070 and <i>p</i> = 0.256, respectively), and, in SSc patients only, a strong negative correlation was observed between leptin and adiponectin serum levels (<i>r</i> = -0.314; <i>p</i> = 0.0312).
Among them, six of which were studied for the serum adiponectin levels in SSc patients, six of which were studied for the serum leptin levels in SSc patients, and two of them were studied both for serum adiponectin levels and serum leptin levels in SSc patients.
