The middle column shows the percentage of patients who had ever been anemic in pregnancy (at least 1 hemoglobin <105), stratified according to severity of anemia. The denominator is the total number of patients who had a hemoglobin test result in pregnancy (34 028). Multiple anemic hemoglobin levels for a single patient were accounted for separately. The far right column shows the frequency of ferritin checks stratified by anemia severity category. The denominator is the total number of patients in that anemia severity category. Tests were ordered any time between the index date and 32 weeks following it.
