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
Objectives: Rabies, a neglected zoonotic encephalitis caused by lyssaviruses, claims around 59,000 lives annually. PCR-based methods are pivotal for laboratory confirmation of rabies in humans and animals. The LN34 pan-lyssavirus real time PCR assay has demonstrated good diagnostic performance in detecting rabies viral RNA in extensive evaluations with animal brain tissues. However, its application has not been adequately evaluated on human samples. Methods: This study assessed the utility of the LN34 assay on human brain tissues, and antemortem samples such as cerebrospinal fluid, saliva and nuchal skin. Furthermore, this assay was also evaluated using postmortem dog saliva samples, in addition to animal brain samples. Results: Compared to the gold-standard fluorescent antibody test (FAT), the LN34 assay showed 100 % sensitivity and specificity for both human and animal brain samples. For human antemortem samples, there was perfect agreement between the LN34 assay and routine real-time RT-PCR for detection of rabies virus (RABV). Similarly, there was complete agreement between the two assays when testing dog saliva samples. The sensitivity and specificity of saliva LN34 assay in laboratory-confirmed rabid dogs was 50 and 100 % respectively. Conclusions: The LN34 assay is a suitable alternative for diagnosis and surveillance of rabies in humans and animals in an area endemic for rabies lyssavirus.
