1 · What the graph read from it

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.

2 · The registry

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

Monitoring yellow fever in non-human primates (NHPs) is an early warning system for sylvatic yellow fever outbreaks, aiding in preventing human cases. However, current diagnostic tests for this disease, primarily relying on RT-qPCR, are complex and costly. Therefore, there is a critical need for simpler and more cost-effective methods to detect yellow fever virus (YFV) infection in NHPs, enabling early identification of viral circulation. In this study, an RT-LAMP assay for detecting YFV in NHP samples was developed and validated. Two sets of RT-LAMP primers targeting the YFV NS5 and E genes were designed and tested together with a third primer set to the NS1 locus using NHP tissue samples from Southern Brazil. The results were visualized by colorimetry and compared to the RT-qPCR test. Standardization and validation of the RT-LAMP assay demonstrated 100% sensitivity and specificity compared to RT-qPCR, with a detection limit of 12 PFU/mL. Additionally, the cross-reactivity test with other flaviviruses confirmed a specificity of 100%. Our newly developed RT-LAMP diagnostic test for YFV in NHP samples will significantly contribute to yellow fever monitoring efforts, providing a simpler and more accessible method for viral early detection. This advancement holds promise for enhancing surveillance and ultimately preventing the spread of yellow fever.
