Association between presence of latrine and unclean child face on the prevalence of active trachoma among children aged 1 to 9 years in low-income setting: A systematic review and meta-analysis.
Synthesis in PloS one, 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
backgroundTrachoma is the leading infectious cause of blindness worldwide, primarily affecting populations in low-income countries with poor sanitation and hygiene conditions. The World Health Organization has set a goal to eliminate trachoma as a public health problem. However, progress towards this goal has been uneven across different regions. This systematic review and meta-analysis aimed to synthesize the available evidence on the association between the presence of latrine facilities and unclean child faces with the prevalence of active trachoma among children aged 1 to 9 years in low-income country settings. The findings from this study can help guide the design of more targeted interventions to reduce the burden of trachoma in vulnerable populations. MATERIALS AND
methodsA total of 2695 articles were searched from PubMed, Hinari, African Online Journals, Google, Google Scholar, Science Direct, and Semantic Scholar and exported to STATA version 17 for analysis. The levels of heterogeneity among studies were assessed using I2 and p-values. The findings of the meta-analysis were presented using a table, graph, and forest plot with a 95% confidence interval. A P-value of less than 0.05 was considered statistically significant.
resultAmong 2695 articles searched, 16 of them were selected for meta-analysis. The pooled prevalence of active trachoma was 21.10 (95% CI; 14.18, 28.02). The finding indicated high heterogeneity among the included studies (I2 =99.3%, p<0.0001). There was a statistically significant association between the presence of a latrine (POR=0.10, 95% CI: 0.00, 0.19) and unclean child face (POR=1.30, 95% CI: 1.08, 1.53) and the pooled prevalence of active trachoma among children aged 1 to 9 years in low-income countries.
conclusionThe present study revealed that the pooled prevalence of active trachoma was high as compared to the WHO trachoma eradication goal. The presence of latrine facility and unclean child face were significantly associated with the prevalence of active trachoma among children aged 1 to 9 years in low-income countries. Hence it is recommended to improve access to latrines, promote child facial hygiene, and intensify overall trachoma control in low-income countries.
