Height was measured using a rigid stadiometer (TTM stadiometer; Tsutsumi Co., Ltd., Tokyo, Japan). Weight was measured using calibrated scales (AD-6107NW; A&D Medical Co., Ltd., Tokyo, Japan). BMI was calculated as body weight in kilograms divided by the square of body height in meters. Waist circumference was measured at the umbilical level at the end of exhalation in a standing position. Handgrip strength was measured using a Smedley analog hand dynamometer (No. 04125; MIS, Tokyo, Japan) with both hands in a standing position. The measurements were first performed for the dominant hand. Subjects performed two maximum attempts for each hand with approximately 1-min rest period between trials. We used the average handgrip strength in kilograms. According to a consensus report of the Asian Working Group for Sarcopenia, we defined sarcopenic subjects as follows: age, ≥ 65 years and handgrip strength, <26 kg for men and <18 kg for women^{49 (link)}.
Blood pressure was measured in a seated position using an automatic sphygmomanometer (HBP-9020; Omron Co., Ltd, Tokyo, Japan). Arterial stiffness was examined by measuring both baPWV and AIx₇₅ using a pulse pressure analyzer (BP-203RPE; Nihon Colin, Tokyo, Japan) and a digital automatic sphygmomanometer (HEM-9000AI; Omron Co., Ltd, Tokyo, Japan), respectively.

Routine anthropometric measurements were performed by trained examiners. Height and weight were measured to the nearest 0.1 cm and 0.1 kg, respectively, while the participants were asked to wear light clothing and stand barefoot. Body mass index (BMI) was calculated as weight (kg)/height (m)². After the participants rested quietly for a minimum of 5 min, systolic and diastolic blood pressures (SBP and DBP, respectively) were measured using a standard electronic sphygmomanometer (HBP-9020; OMRON, Dalian, China). Data on sex, age, ethnicity, and individual history of disease were collected using a questionnaire. Fasting (over 12 h) blood samples were collected from each participant and sent to the clinical laboratory of Tongji Hospital for standard biochemical measurement within 2 h of collection. Total cholesterol (TC), TG, low-density lipoprotein cholesterol (LDL-C), HDL-C, fasting plasma glucose (FPG), uric acid, and creatinine were determined using standard laboratory procedures.

Blood pressure was measured twice using an automatic blood-pressure meter (HBP-9020, OMRON (China) Co., Ltd.) after participants were seated for at least 10 mins. The average of two measurements was recorded for further analysis. Total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured as well. The estimating glomerular filtration (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration 2-level race equation [18 (link)]. All the biochemical measurements were performed in the Clinical Laboratory of Ren Ji Hospital.

We evaluated patient BP and PR using an automated oscillometric upper-arm BP monitoring device (HBP-9020, Omron Co., Kyoto, Japan). The participants were seated in a quiet room at a comfortable temperature (22–25 °C) and were instructed to avoid talking during the procedure. In this study, we evaluated the BP and PR of patients in a stable situation without a desire to urinate after visiting our hospital. The BP measurements were started after the participants had rested for 5 min. The participants sat on a chair with their legs uncrossed and their feet flat on the floor. All BP measurements were performed on the participant’s left arm at the level of the heart. The data were measured twice at intervals of approximately 2 min, and the average value was used as the measured value.
