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
Post-kala-azar dermal leishmaniasis (PKDL) is a neglected tropical disease that can develop after treatment of leishmaniasis. It causes significant health risks and serves as a reservoir, perpetuating transmission. Current information on PKDL characteristics is crucial for effective disease management and control. This study aimed to describe clinical and epidemiological characteristics of PKDL patients in eastern Sudan. A retrospective cross-sectional study was conducted on suspected PKDL patients (N = 37) at a tertiary hospital in eastern Sudan. Blood samples were tested for anti-rK39 antibodies to confirm the diagnosis of the disease. Demographic, clinical, and epidemiological data of the PKDL patients were gathered and analyzed. Most PKDL cases (69.4%) came from specific locations involving one ethnic group (94.6%), mainly affecting young males (54.1%). A family history of PKDL was noted in only 27.0% of cases; 51.4% developed PKDL within 1 month after visceral leishmaniasis (VL) treatment. Most cases (56.8%) were grade 1 (a low level of parasitic load), predominantly featuring macular (51.4%), papular (18.9%), and nodular (13.5%) lesions. All patients had skin rashes; 91.9% exhibited no fever, and 29.7% reported itching. Lesions appeared within a month after VL treatment, with most patients recovering spontaneously within 3-18 months. PKDL was particularly prevalent in specific regions and ethnic groups, namely the Masaleet and Dago tribes. These findings can enhance PKDL understanding and management in the region.
