We agree that analyzing our data on repeat chlamydia infections by treatment modality or compliance or both may have provided interesting information on efficacy. Although data on treatment regimen were not collected in our study, 2 recent reports compared the efficacy of doxycycline vs azithromycin and found them to be comparable, with treatment failures of less than 5% at 2 to 4 weeks after therapy.1- 2 Therefore, we do not believe differentiation of results by treatment regimen or reported patient compliance would have altered our findings.
