As the ambulatory management of PSP is widely accepted as being safe, we used this group as a comparator group to assess the outcomes of patients with SSP. For statistical comparison, t-tests and Mann-Whitney U tests were used for continuous data depending on whether they were normally distributed, and the χ2 test for binary outcomes. For all tests, a significance threshold of 0.05 was applied.
