3.1 Demographic characteristics of the study population
A total of 71 patients were enrolled in the study, of whom 37 were ESRD patients on regular HD and 34 were healthy controls. The systolic (119.94±10.32 vs 150.76±19.67; p < 0.001) and diastolic (76.68±7.03 vs 90.81±12.14; p <0.001) blood pressures were found to be higher in the ESRD group. The mean age of the ESRD group was found to be higher than the heathy group (42.03±11.50 vs 51.68±15.98, p=0.005), while no difference was observed between the groups in terms of BSA, gender, and heart rate. Laboratory tests showed an increase in serum urea (5.00±0.84 vs 17.27±5.89; p<0.001) and creatinine (63.41±12.29 vs 606.81±138.09;p<0.001) and a significant decrease in eGFR(102.40±5.36 vs 7.87±1.93;p<0.001) in the ESRD group. Among the ESRD patients, 30 had hypertension, 8 had diabetes mellitus, and 5 had hyperlipidemia (Table1).
