Antibiotic Prescriptions by Visits.

Number of ARI visits for which antibiotics were given (“Prescribed” rows) or withheld (“Not Prescribed” row) either in accordance with (“Warranted” columns) or against guideline recommendations (“Unwarranted” columns). Columns further separate the visits by 1) study site (Intervention vs. Control Site); 2) time periods (pre-intervention year (“2002”) vs. post-intervention years (“2003–6”)); and 3) by whether or not the antibiotics prescribed were those targeted by the intervention (“Targeted” vs. “Other”).
