a Comparison of leptin plasma concentrations at the individual time points between multiple trauma patients (MT) and control group (Control). Depiction of the concentrations as box-and-whisker plots with minimum/maximum value and + depicting the mean value. Statistical analysis of the data was performed by Mann–Whitney U test (* = p < 0.05; ** = p < 0.01). n_{multiple trauma 0 h = 12}, n_{multiple trauma 6 h = 14}, n_{multiple trauma 24 h = 13}, n_{multiple trauma 48 h = 12}, n_{multiple trauma 72 h = 12}, n_{control group = 14}. b Comparison of leptin plasma concentrations at the individual time points between multiple trauma patients without (MT) and multiple trauma patients with multiple organ failure (MT + MOF). Depiction of the concentrations as box-and-whisker plots with minimum/maximum value and + depicting the mean value. Statistical analysis of the data was performed by Mann–Whitney U test (* = p < 0.05). n_{MT 0 h = 9}, n_{MT + MOF 0 h = 3}, n_{MT 6 h = 10}, n_{MT + MOF 6 h = 4}, n_{MT 24 h = 9}, n_{MT + MOF 24 h = 4}, n_{MT 48 h = 8}, n_{MT + MOF 48 h = 4}, n_{MT 72 h = 8}, n_{MT + MOF 72 h = 4}
