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 caused by different species of Leishmania is transmitted by Phlebotominae sandflies. This disease remains a public health concern in Iran. Therefore, the present study aimed to examine Leishmania infection in sandflies and reservoir rodents in six rural regions of Nahavand, located in western Iran. From May to October 2022, sandflies and rodents were collected and identified at the species level. Additionally, rodents' skin lesions and earlobe specimens were collected separately for microscopic and molecular examination. All specimens were tested for Leishmania DNA by PCRs targeting the parasite's ITS-2 and 18S rRNA gene and positive were Sanger sequenced. A total of 3396 sandflies belonging to seven subgenera and 11 species, i.e., Phlebotomus papatasi (42.7%), P. major (20.6%), P. mascitti (0.3%), P. neglectus (0.2%), P. alexandri (0.2%), P. turanicus (0.3%), Sergentomyia murgabiensis (18.1%), S. dentata (10.5%), S. theodori (5.8%), S. antennata (1.1%), and S. pawlowski (0.1%) were identified. Based on the species population, 29 pools of sandflies were examined for the presence of Leishmania DNA using conventional PCR (cPCR), and individual DNAs were tested when positive. Leishmania major DNA was detected in two P. papatasi and Leishmania sp. in one P. major individual sandfly. This is the first report of Leishmania infection in sandflies from Hamadan province. The captured rodents (n = 61) belonged to four families and seven species, i.e., Arvicola amphibius (37.7%), Mus musculus (29.5%), Microtus socialis (13.1%), Apodemus sylvaticus (11.5%), Talpa davidiana (4.9%), Apodemus witherbyi (1.6%), and Rattus norvegicus (1.6%). Microscopic and molecular examinations of the rodent lesions and earlobes scored negative results. The presence of Leishmania in the Phlebotominae sandflies in Nahavand indicates a potential threat to humans and animals in the region. Regular monitoring and examination of the sandflies' population and timely diagnosis and treatment of new patients are strongly recommended.
