We compared the basic information of the 2 groups of patients and found that there was no significant difference between the 2 groups in gender, age, obesity (BMI > 23), smoking history, red blood cell count, hemoglobin, total serum protein, serum albumin, blood glucose, and glycated serum protein (Table 1, P > .05). Here, ALB is linked to obesity due to melanocortin 4 receptor deficiency.
