First Report of On-Site Detection of Cucurbit Leaf Crumple Virus by an Optimized RPA-Lateral Flow Assay with an Alternative Endonuclease.

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
Rapid, simple, and robust diagnostics are essential for effectively controlling the spread of plant viruses and mitigating their impact. Although recombinase polymerase amplification-lateral flow test (RPA-LFT) diagnostics currently offer high sensitivity and specificity, they rely on the Nfo endonuclease enzyme and require an expensive heat block. In this study, we present the development of a molecular diagnostic test for cucurbit leaf crumple virus (CuLCrV) using an RPA-LFT assay that employs an alternative endonuclease enzyme instead of Nfo. This alternative endonuclease demonstrates comparable functionality to Nfo and achieves a detection limit of 10 viral copies in plant samples and whiteflies. The assay can be performed using a battery-powered mini heat block, ensuring scalability and cost-effectiveness. Notably, the unavailability of commercially accessible Nfo endonuclease enzymes underscores the necessity for an alternative enzyme for RPA-LFT assay development. The RPA-LFT assay eliminates the need for nucleic acid purification and provides results within approximately 30 min from sample collection. The integration of this new endonuclease into the RPA-LFT assay represents an advancement towards on-site detection of plant viruses, enabling early-stage management of viral infections.
