Epidemiological surveillance of canine visceral leishmaniasis in a municipality in the Western Amazon.

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
Visceral leishmaniasis is a zoonotic disease of public health importance in Brazil, with expansion into peri-urban areas. This cross-sectional study evaluated 450 dogs in a municipality of the Western Amazon, Brazil, using TR-DPP® serology, ELISA confirmation, hematological analysis, PCR targeting the Hsp70 gene, and entomological surveys with CDC light traps. A total of 45 dogs (10%) were seroreactive, and 34 were confirmed by ELISA. Hemoparasites such as Babesia spp. were detected. All pooled samples were negative by PCR. Six species of phlebotomine sand flies were identified, including Nyssomyia antunesi and Migonemyia migonei. The findings suggest early exposure of dogs in an area of emerging epidemiological risk, highlighting the importance of integrated surveillance strategies.
