Cubic spline curves for the association between cumulative fluid balance and 90-day mortality. a Cubic spline curve representing patients with cardiovascular disease. b Cubic spline curve representing patients with respiratory disease. c Cubic spline curve representing patients with other disease. Dashed line = median cumulative fluid balance, dark gray area = IQR, blue line = permissive threshold of cumulative fluid balance
