Association of the primary end point (absolute change in plasma sodium concentration) with covariates. (A) baseline plasma sodium concentration, (B) baseline plasma osmolality concentration, (C) severity of hyponatremia. (D) Shows course of plasma glucose levels during intervention. (A and B) Indicated lines are the respective linear regression lines. (C and D) Boxes contain the 25% through 75% quantiles (spanning the IQR), and the thick horizontal line is the median. Whiskers indicate the most extreme values lying within the box edge and 1.5 times the IQR. All eventual further values are plotted as individual points (outliers).
