SummaryBackgroundIn trachoma control programmes, azithromycin is distributed to
treat the strains of chlamydia that cause ocular disease. We aimed to compare
the effect of annual versus twice-yearly distribution of azithromycin on
infection with these strains.MethodsWe did a cluster-randomised trial in 24
subdistricts in northern Ethiopia, which we randomly assigned to receive annual
or twice-yearly treatment for all residents of all ages. Random assignment was
done with the RANDOM and SORT functions of Microsoft Excel. (Source: LANCET)
