Endemicity, disability and neglect: Leprosy in Colombia 2007-2020.
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. 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
backgroundDisability due to leprosy in Colombia is a neglected public health problem. This work aims to describe the magnitude of leprosy in Colombia, the spatiotemporal distribution of the disability and explore the potential relationship between individual and treatment delay characteristics with degrees of disability.
methodsOfficial leprosy data in Colombia between 2007 and 2020 were analyzed. The distribution of the grade 2 disability (G2D) rate was estimated. A Poisson spatiotemporal model was constructed to form clusters of municipalities with risk of G2D. A multinomial logistic regression model was used to quantify the relationships between patient characteristics and disability grades 1 (G1D) and 2 (G2D).
resultsDuring the fourteen-year period, 5240 leprosy cases were registered (median age: 51 years, IQR: 35-63), of which 63.8% (n = 3341) were men. The proportion of multibacillary forms was 65.9% (n = 3453), 47.1% (n = 2468) for grade 0 disability (G0D), 18.4% (n = 966) for G1D and 9.7% (n = 507) for G2D. Three clusters and 10 municipalities were detected for the municipal rate of G2D. The national rate of G2D ranged between 0.03/100,000 inhabitants in 2010 and 0.05/100,000 inhabitants in 2020. The prevalence ratio of G1D and G2D was significant in individuals aged 60 years or older, men, from the subsidized or uninsured health system, who had relapses, multibacillary type and in whom the delay between the onset of symptoms and treatment was 7-12 years.
conclusionIn the context of leprosy elimination in Colombia, the prevalence of disability is high and heterogeneous in time and space. It is recommended to coordinate the necessary actions to "revitalize" the active epidemiological surveillance in the prioritized municipalities and strengthen the program including improving early detection, treatment and individual follow-up of patients with disabilities.
