Figure 1 Outcomes and use of second therapies in patients with baseline serum sodium concentrations <130 mEq/L treated with fluid restriction or isotonic saline as monotherapy. (A) Patients with laboratory-diagnosed syndrome of inappropriate antidiuretic hormone secretion initially treated with fluid restriction as monotherapy. (B) Patients with laboratory-diagnosed syndrome of inappropriate antidiuretic hormone secretion initially treated with isotonic saline as monotherapy. The decision to initiate a second treatment or not and the selection of any such treatments were made by the patients' treating physicians without input from the investigators. All serum [Na+] values are mean ± standard deviation in mEq/L. FR = fluid restriction; HS = hypertonic saline; [Na+] = serum sodium concentration; NS = isotonic saline; SIADH = syndrome of inappropriate antidiuretic hormone secretion; TO = tolvaptan. aPretreatment value. bSuccess defined as proportion of patients with [Na+] increase in [Na+] ≥5 mEq/L.

Figure 2 Median length of hospital stay for all patients with syndrome of inappropriate antidiuretic hormone secretion and the US and EU cohorts separately. P <.05: EU-FR vs tolvaptan; HS vs tolvaptan. FR = fluid restriction; HS = hypertonic saline; LOS = length of stay; NS = isotonic saline; TO = tolvaptan.
