Input: We included two cluster-RCTs, which provided data from 2447 participants. Both trials were conducted in areas endemic to trachoma: Northern Australia and Tanzania. The follow-up period was three months in one trial and 12 months in the other; both trials had about 90% participant follow-up at final visit. Overall the quality of the evidence is uncertain due to the trials not reporting many design methods and the differences in outcomes reported between trials. Face washing combined with topical tetracycline was compared with topical tetracycline alone in three pairs of villages in one trial. The trial found that face washing combined with topical tetracycline reduced 'severe' active trachoma compared with topical tetracycline alone at 12 months (adjusted odds ratio (OR) 0.62, 95% confidence interval (CI) 0.40 to 0.97); however, the trial did not find any important difference between the intervention and control villages in reducing other types of active trachoma (adjusted OR 0.81, 95% CI 0.42 to 1.59). Intervention villages had a higher prevalence of clean faces than the control villages among children with severe trachoma (adjusted OR 0.35, 95% CI 0.21 to 0.59) and any trachoma (adjusted OR 0.58, 95% CI 0.47 to 0.72) at 12 months follow-up. The second trial compared eye washing to no treatment or to topical tetracycline alone or to a combination of eye washing and tetracycline drops in children with follicular trachoma. At three months, the trial found no evidence of benefit of eye washing alone or in combination with tetracycline eye drops in reducing follicular trachoma amongst children with follicular trachoma (risk ratio (RR) 1.03, 95% CI 0.96 to 1.11; one trial, 1143 participants). There is evidence from one trial that face washing combined with topical tetracycline may be effective in reducing severe active trachoma and in increasing the prevalence of clean faces at one year follow-up. Current evidence is inconclusive as to the effectiveness of face washing alone or in combination with topical tetracycline in reducing active or severe trachoma.
Output:

We included two randomized controlled trials with a total of 2560 participants set in Australia and Tanzania. One trial compared a combined strategy of face washing plus tetracycline (an antibiotic) ointment with tetracycline ointment alone for up to one year. The second trial compared four intervention groups for three months in children who already had follicular trachoma: a combined strategy of face washing plus tetracycline eye drops, face washing alone, tetracycline eye drops alone, and no treatment. The evidence is current to January 2015. Both trials reported the number of children with active trachoma as an outcome measure; one trial also reported the number of children with severe trachoma and the percentage of clean faces after one year. One trial reported that face washing was effective in increasing facial cleanliness and in reducing severe trachoma at one year; the second trial did not show that eye washing alone or in combination with tetracycline eye drops reduced follicular trachoma amongst children who had follicular trachoma at time of enrollment. The two included trials were of uncertain risk of bias due to not reporting many aspects of the trial designs.
