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

In 2024, Monkeypox virus (MPXV) clade I has triggered outbreaks in several countries world-wide. MPXV clade I demonstrates enhanced virulence and transmissibility, with a case fatality rate reaching 10%. In response, we have developed a one-pot detection assay specifically targeting MPXV clade I, combining recombinase polymerase amplification (RPA) and the CRISPR/Cas12a system. The assay can be completed within 40 min and achieved a 95% limit of detection (LOD95) of 27.16 copies/μL. No cross-reactivity was observed with MPXV clade II or other tested viral templates, including Vaccinia virus (Tiantan strain). A preliminary room-temperature evaluation showed that the assay retained detectable performance at 25°C, supporting its potential use in equipment-limited settings. The assay also showed good intra-assay and inter-assay repeatability for recombinant plasmid templates, with all coefficient of variation (CV) values below 10%. In simulated clinical samples, the RPA-CRISPR/Cas12a assay detected more low-concentration plasmid-spiked samples than quantitative polymerase chain reaction (qPCR). These results indicate that the established assay is specific, sensitive, repeatable, and easy to perform, providing a practical tool for field-based screening and decentralized detection of MPXV clade I.
