Severity Outcomes

Severity flags recorded across the 134,640 FAERS submissions that named Dyural 40 Kit. Each bar shows the count of those reports carrying that flag. A single case can carry more than one (a hospitalization that became life-threatening, for example), so these bars are independent rates - they don't sum to 100%. Inclusion of a case under any flag does not establish that the drug caused the outcome.
