Impact of trachoma elimination efforts in afar regional state, Ethiopia: survey findings from 26 evaluation units.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFollowing interventions to eliminate trachoma in the Afar region of Ethiopia, our goal was to reassess the prevalence of trachomatous trichiasis (TT) and trachomatous inflammation-follicular (TF) at the woreda level, and to identify factors associated with the disease.
methodsCross-sectional community-based surveys were conducted in 26 trachoma-endemic woredas, employing a standardized approach. Households were selected as the secondary sampling unit. Surveys involved interviews with household heads, direct assessment of water, sanitation, and hygiene (WASH) access, and clinical examination of eligible household members for trachomatous trichiasis (TT) and trachomatous inflammation-follicular (TF).
resultOverall, 18 out of the 26 woredas (69%) achieved the World Health Organization-recommended threshold for active trachoma elimination, with a prevalence of trachomatous inflammation-follicular (TF) below 5% in children aged 1-9 years. Additionally, 14 woredas (54%) met the threshold for trachomatous trichiasis (TT) elimination, with a prevalence of TT cases unknown to the health system below 0.2% in adults aged 15 years and older. However, access to improved drinking water sources within a 30-minute trip was limited to only 17% of households, and merely 9% had access to improved latrines. Addressing these WASH (Water, Sanitation, and Hygiene) challenges remains critical for sustaining progress in trachoma control and achieving long-term public health improvements in the Afar region.
conclusionIn seven woredas, further rounds of antibiotic mass drug administration are required, complemented by initiatives to promote facial cleanliness and improve environmental conditions. Additionally, surgical campaigns for trachomatous trichiasis (TT) are needed in 12 woredas. There is a critical need to enhance access to improved Water, Sanitation, and Hygiene (WASH) facilities across all surveyed woredas to consolidate gains in trachoma control and achieve sustained public health improvements.
