The permutation-based p-value and its 95% confidence interval (ci), and log rank score statistics are provided for each combination of region and symptom. The rows with a p-value < 0.05 are in bold. P-values were not adjusted for multiple comparisons. For tertiles with sample size >15, the percent of participants with resolved symptoms is reported at 6 months and 12 months, based on Turnbull intervals.
