P values show the overall p value for the insurance type across the three time periods, and p values meeting the significance threshold of p<0.05 are emphasized in bold. Symbols show which two-way comparisons were significant at p<0.05. Total numbers of patients in the rows may not add up to the column totals because patients are included more than once if they used multiple types of insurance.
