Comparison of observation periods between stone formers without and with 24-hour urine testing. For stone formers who did not complete 24-hour urine testing, we used the date of the initial stone diagnosis as a reference for comparison for the date of the initial 24-hour urine test in stone formers who completed 24-hour urine testing. We then compared filled prescriptions in the observation periods between stone formers with and without 24-hour urine testing.
