Spatial epidemiologic trends of cutaneous leishmaniasis in Rio de Janeiro State, Southeast Brazil, 2001-2020.

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
Cutaneous leishmaniasis (CL) has substantial epidemiological and clinical differences depending on host characteristics, Leishmania species and geographic areas. CL in Rio de Janeiro State was evaluated. Mandatory notifications of confirmed cases from 2001-2020 were analyzed considering sociodemographic and clinical variables, temporal trends, the Cutaneous Leishmaniasis Composite Indicator (CLCI) for each affected city in relation to the total of affected cities in the state, and each triennium from the beginning to the end of the time series (2001-2003, 2002-2004 until 2018-2020, sequentially). The number of cases decreased over time. High average incidence rates occurred in contiguous cities from the Southernmost to the Northernmost regions of Rio de Janeiro State, following areas where the Atlantic Forest persists. The CLCI showed temporal variations in the intensity of the risk of CL in the affected cities. Rio de Janeiro city was the only one with intense or very intense risk of CL throughout the studied period. The disease predominantly affected people residing in urban areas and in the middle age groups (20-59 years). CL also predominated in males, regardless of age. The mucosal clinical form was also significantly associated with men, with an 80% chance of them being more affected than women. Regarding diagnostic tests, the Leishmanin Skin Test showed higher positivity than the direct parasitological exam and the histopathological exam. No differences regarding cure between sexes were found. This study may guide control actions in areas where they are most needed in Rio de Janeiro State.
