Box plots for the absolute change in PGE2 by intervention arm. After adjusting for the interim analysis and multiple comparisons, the nominal significance level was As shown, the higher-dose aspirin + PPI intervention resulted in a significant decrease in PGE2 values as compared with aspirin placebo + PPI (P = .020), whereas the lower-dose aspirin + PPI intervention did not differ significantly from aspirin placebo + PPI (P = .096).
