We also investigated a seasonal variation in BP for patients of different gender types, of different age groups, with diabetic nephropathy (DN), and with non-DN having HD. Multiple linear regression models were used to explore the associations between BP and climatic parameters.<h4>Results</h4>In 2019, a total of 367 patients had received HD therapy in the Longwen HD unit. We included nearly 40,000 pre-dialysis BP measurements. The result of our study demonstrated a clear seasonal variation in pre-dialysis BP in general patientFrontiers in cardiovascular medicine820483https://www.ebi.ac.uk/biostudies/studies/S-EPMC8971928biostudies-literatureSeasonal Variation: A Non-negligible Factor Associated With Blood Pressure in Patients Undergoing Hemodialysis.PMC8971928Lan SWu ZZhang YZhang XChen CChen SfalseSeasonal Variation: A Non-negligible Factor Associated With Blood Pressure in Patients Undergoing Hemodialysis.<h4>Objective</h4>To investigate a seasonal variation in blood pressure (BP) for patients undergoing hemodialysis (HD).<h4>Methods</h4>In this retrospective study, we exported all BP measurements from the information system to investigate a seasonal variation of BP.
