Comparison of annual versus twice-yearly mass azithromycin treatment for hyperendemic trachoma in Ethiopia: a cluster-randomised trial.

The article presents a study which aims to compare the effect of azithromycin distribution on an annual or twice-yearly frequency in the control of hyperendemic trachoma in Ethiopia. It states that the study used a cluster-randomised trial which randomly assigned annual or twice-yearly treatment of trachoma in northern Ethiopia subdistricts.
