The Gravity of Flow study evaluated an in-house developed urine production gauge (UPG), designed as a\u00a0reusable-cost system compatible with standard urine bags for automatic, continuous UO measurement and Electronic Health Record (EHR) integration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This single-centre observational study enrolled 25\u00a0cardiology patients (519\u202fh) with indwelling urine catheters. To assess completeness and volume accuracy, UPG performance was compared against standard manual urine charting and a\u00a024-hour container (gold standard).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The UPG achieved superior median completeness compared to manual charting (100% vs.\u00a040%,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&lt;\u20090.001). The device demonstrated high accuracy (median absolute percentage error 2.3%) and minimal bias (median \u22123\u202fmL), meeting \u00b15% equivalence criteria (78.3% within bounds).
