Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change in from urine calcium from baseline (time 0) and 2-weeks (completion) after oral phosphate (250mg twice daily) supplementation | 2 weeks | Change in 24-hour urine calcium (mg/day) from baseline to the end of 2 weeks of oral neutral phosphate (250 mg twice daily). Urine is collected over 24 hours at home before the baseline visit and again at 2 weeks, and calcium is measured by Litholink (Labcorp). The change is calculated for each participant as the 2-week value minus the baseline value. |
| Secondary | Change in Urine Calcium Oxalate Supersaturation | 2 weeks | Change in 24-hour urine calcium oxalate supersaturation from baseline to the end of 2 weeks of oral neutral phosphate (250 mg twice daily). Supersaturation is calculated with the EQUIL2 program from the 24-hour urine chemistries measured by Litholink (Labcorp). The change is the 2-week value minus the baseline value for each participant. |
| Secondary | Change in Urine Calcium Phosphate Supersaturation | 2 weeks | Change in 24-hour urine calcium phosphate supersaturation from baseline to the end of 2 weeks of oral neutral phosphate (250 mg twice daily). Supersaturation is calculated with EQUIL2 from the 24-hour urine chemistries measured by Litholink (Labcorp). The change is the 2-week value minus the baseline value for each participant. |
