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
objectiveTo assess the impact of COVID-19 on the incidence of visceral leishmaniasis in children and adolescents living in the Northeast region of Brazil.
methodsTime series study with data from the Notifiable Diseases Information System, from the study of population estimates by municipality, age and sex from 2000 to 2021, and from the Brazilian Institute of Geography and Statistics. An analysis of the temporal trends of the incidence rate was performed using the Joinpoint software, calculating the average annual percentage variation (AAPV) and its 95% confidence intervals (95%CI). The percentage variation in incidence rates from 2020 to 2022 was also calculated to check whether they were below or above what was expected for the year and territory.
resultsFrom 2007 to 2022, 13,890 new cases of visceral leishmaniasis were reported in children and adolescents in Northeast Brazil. Changes in trends were identified with the addition of the years of the COVID-19 pandemic, from 2020 to 2022, in the Northeast: AAPV (2007-2019) 0.44; 95%CI -2.23; 3.18; AAPV (2007-2022) -7.95; 95%CI -13.63; -1.88), Pernambuco: AAPV (2007-2019) 6.77; 95%CI 2.04; 11.71; AAPV (2007-2022) -1.40; 95%CI -8.75; 6.53 and Alagoas: AAPV (2007-2019) 11.51; 95%CI 4.90; 18.53; AAPV (2007-2022) -1.33; 95%CI -14.89; 14.40).
conclusionThe Northeast and its states where changes in temporal trends were observed after the COVID-19 pandemic are priorities for the intensification of actions to combat and control the disease.
