Data are number (%), unless otherwise indicated. ESR=erythrocyte sedimentation rate. The “any” category under exposure history and comorbid condition refers to the number of cases in which this history was provided in the case presentation. Cases might have had more than one exposure history or comorbid condition. Therefore, the numbers do not necessarily add up to 34.
