*Statistically Significant for Fisher’s exact test, when p < 0.05; 1: no CR among ATB users, only PR. 2: this is measured at the level of each ATB use, not at the individual patient-level. CR Complete response, PR Partial response, PD Progressive disease, SD Stable disease, RTI Respiratory tract infection, including bronchitis, pneumonia, upper respiratory tract infection, and sinusitis. Other reasons include patients taking antibiotics for acne, biopsy, cholangitis, colitis, ear cellulitis, leukocytosis, metastasis, rash, urinary tract infection, prophylaxis. Duration of antibiotic use for each reason was not conducted at patient-level, but instead calculated with antibiotic-use level analysis. Each patient may have overlapping antibiotic use; each use was treated as a single observation
