Community-directed treatment with ivermectin in Maridi, South Sudan: Impact of an onchocerciasis awareness campaign and bi-annual treatment on therapeutic coverage.
Article in PLoS neglected tropical diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundA high onchocerciasis disease burden and a low coverage of community-directed treatment with ivermectin (CDTI) have been observed in many parts of South Sudan. In the Maridi County, CDTI was re-introduced in 2017 and various interventions implemented to improve coverage.
methodsThrough successive community-based surveys, we investigated whether an onchocerciasis awareness campaign and a switch from annual to bi-annual distribution of ivermectin in Maridi County increased CDTI coverage. We also reviewed the evolution of ivermectin distribution in Maridi since 2017 and identified the determinants for ivermectin uptake.
resultsFor past years in Maridi, CDTI programme performance has been highly variable due to security concerns, limited funding, misconceptions about ivermectin, and poor organisation of mass treatment campaigns. Community-based surveys conducted between 2018 and 2024 in Maridi found that upon switching from annual CDTI (2017-2019) to bi-annual CDTI (2021 onward), therapeutic coverage significantly increased from 40.8% in 2017 to 70.3% in 2023. Lower age, male gender, more CDTI information sources, and awareness of a link between onchocerciasis and epilepsy were all associated with increased uptake of ivermectin.
conclusionThis study showed that with reinforced awareness raising accompanying biannual CDTI, a higher ivermectin treatment coverage is achievable. The findings present an opportunity for the health system to advance its onchocerciasis elimination scheme in remote, conflict-stricken communities in South Sudan.
