(2) levofloxacin 750 mg daily for 5 d; or
(3) levofloxacin 500 mg daily; or
(4) moxifloxacin 400 mg daily for 7-14 days for subjects allergic to ceftriaxone or azithromycin or according to physician discretion.

|Risk of bias
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
In addition to all available versions of the published article, pre-print article, the study registry, protocol and data from direct contact to authors were used in data extraction and risk of bias assessment. The study achieved the target sample size reported in the registry. There is no change from the trial registration in the intervention and control treatments. No pre-specified statistical analysis plan is available. There is no change from the trial registration in the primary outcome. Some secondary outcomes in the report are not present in the registry. One secondary outcome stated in the paper, 'the proportion of discharge by day 14', was not reported.
