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
backgroundLeishmaniasis is an emerging vector-borne disease that occurs in Thailand. Although Leishmania (Mundinia) parasites, the causative agents of the disease have been identified, the vectors of the disease remain unidentified. In the present study, we collected sand flies from three caves located in endemic areas of leishmaniasis, including Lampang and Chiang Rai in northern Thailand, and Songkhla in southern Thailand.
methodsFemale sand flies were identified on the basis of morphological characteristics and confirmed by cytochrome c oxidase subunit I (COI) sequencing. Sand fly DNA samples were screened for Leishmania, Trypanosoma, and Bartonella DNA by polymerase chain reaction (PCR) on the basis of the ITS1 region of the ribosomal RNA (rRNA), SSU rRNA, and gltA genes, followed by phylogenetic relationships and haplotype diversity analysis.
resultsA total of 557 sand flies were identified, comprising four genera (Sergentomyia, Phlebotomus, Grassomyia, and Idiophlebotomus) and 11 species. Molecular detection of pathogens demonstrated that Leishmania DNA was not detected. However, Trypanosoma DNA was detected in 11 samples of Phlebotomus mascomai from Lampang (7 for T. noyesi), Se. anodontis from Chiang Rai (1 each for T. noyesi and Trypanosoma sp.), and Se. khawi from Songkhla (2 for Trypanosoma sp.). Bartonella DNA was detected in 16 samples of Se. anodontis and Se. barraudi s.l. from Chiang Rai, Se. anodontis from Lampang, and Se. khawi from Songkhla. The novel Bartonella sp. detected in Thai sand flies was phylogenetically related to Bartonella sp. from bats. Genetic diversity analysis showed high haplotype diversity in both Trypanosoma parasites and Bartonella bacteria.
conclusionsThe data from the present study indicate that phlebotomine sand flies could be potential vectors of zoonotic diseases caused by Trypanosoma sp. and Bartonella sp. To our knowledge, this is the first report of the natural infection of Bartonella associated with bats in Thailand, and the presence of T. noyesi and amphibian trypanosomes. However, further investigation is required to elucidate and enhance the understanding of potential vectors and transmission dynamics of pathogens in Thailand, particularly with regard to different seasonality, habitats, and host ranges.
