Figure 2 Odds ratios (boxes) and 95% confidence intervals (bars) for odds of myocardial infarction among aspirin users versus nonusers of aspirin, stratified by frequency of non-aspirin non-steroidal anti-inflammatory drugs (NANSAIDs) and adjusted for same variables as in Figure 1. The p value is for interaction between aspirin and frequency of use of NANSAIDs. Numbers are less than total because of missing information on NANSAID frequency in 19 participants.
