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
backgroundLeprosy control remains challenging in Brazil and has been aggravated by the COVID-19 pandemic.
objectiveTo analyze the impact of the COVID-19 pandemic on the epidemiological scenario of leprosy through the detection rate of new cases, the risk of illness, and the hidden prevalence of leprosy according to high-risk micro-region in Minas Gerais, Brazil.
methodsAn ecological study conducted in the health micro-regions of Minas Gerais, using data on new leprosy cases diagnosed between 2015 and 2023. The annual detection rate of new cases, the risk of illness index and the hidden prevalence of leprosy were evaluated. The time trend was evaluated by calculating the annual percentage change (APC) of the detection rate, based on segmented linear regression, considered significant when it showed
resultsThe state of Minas Gerais showed a significant negative annual increase between 2015 and 2020 (APC = -7.91; 95%CI -21.76--1.72), and in 2020 it showed an inflection point, with an annual increase of 9.91 in the period from 2020 to 2023. When evaluating the hidden prevalence of leprosy in Minas Gerais, we observed a reduction in the estimates' average from 2015-2019 (2.78) to 2020-2023 (2.00). The state as a whole showed an upward trend in the risk of illness, with the average index varying from 0.28 (medium risk) to 0.55 (high risk).
conclusionsThe pandemic has had a considerable and heterogeneous impact on the detection of new cases, as well as on the risk of becoming ill and the hidden prevalence of leprosy, with repercussions for the control of the endemic in populations. There is a need to implement public health policies that prioritize the early identification of cases and ensure that vulnerable populations are monitored.
