aConcordant antibiotic visits include both: a) visits for which antibiotics were warranted and were prescribed, and b) visits for which antibiotics were not warranted and were not prescribed. For the ARI condition “Acute bronchitis only”, all 74 visits were concordant because no antibiotics were prescribed
bPercentages for this column are calculated with Concordant Antibiotic Visits (n = 380) as the denominator
cPercentages for this column are calculated with Discordant Antibiotic Visits (n = 751) as the denominator
dARI conditions are not mutually exclusive, so the column percentages for this section will not total 100%
