Geospatial inequalities in severe leprosy disability in Pernambuco before and during COVID-19.

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
objectiveThe present study therefore aimed to compare and contextualize leprosy indicators in the State of Pernambuco during the pre-pandemic and pandemic periods, to assess the burden of disease using Years Lived with Disability, and to examine its distribution across Pernambuco's various health regions.
methodsThis ecological study used secondary data to compare epidemiological indicators and the burden of leprosy-related disease in the State of Pernambuco, Brazil, before (2017‒2019) and during (2020‒2022) the COVID-19 pandemic, and to examine its distribution among health regions.
resultsThe detection rate of new cases decreased from 33.44 to 24.54 per 100,000 inhabitants, although endemicity remained high in most regions and hyperendemic in Petrolina. The detection rate of new cases with grade 2 disability increased from 7.22 to 8.64 per 1000,000 inhabitants, particularly in the regions of Recife, Caruaru, and Petrolina. Years lived with grade 2 disability increased from 352.76 to 463.06 years.
conclusionDuring the period from 2020 to 2022, the COVID-19 pandemic was associated with significant changes in most leprosy indicators, suggesting an increase in morbidity in the state of Pernambuco, Brazil. Despite the reduction in new leprosy cases due to mobility restrictions, the overburdening of the public health system, and the suspension of active case finding, particularly affecting children and vulnerable populations, there was an increase in hidden prevalence, treatment delays, and disabilities. The behavior of the epidemic in the state of Pernambuco was similar to that observed in Brazil, reinforcing the country's position as the second most affected by leprosy in the world.
