  1. aDefined as any antipyretic medication given on the day of patient data study entry date
  2. bMedication administration record to identify antipyretic use on day of patient study entry date was not found by Health Data Resources for two Case patients. Therefore, denominator used for Cases and Total in this analysis were 103 and 208, respectively
  3. cDefined as any corticosteroid medication given within 7 days of patient data study entry date
