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

backgroundMonkeypox virus (MPXV) infection has garnered significant global attention due to its rising incidence and substantial public health implications. A rapid, sensitive, and accurate diagnostic method is urgently required to enable early intervention and effective management of MPXV outbreaks.

resultsIn this study, we developed a novel one-step assay that integrates loop-mediated isothermal amplification (LAMP) with CRISPR/Cas12b in one-pot for the detection of MPXV. The entire detection process did not require opening the lid of the reaction tube and could be completed within 40 min using extracted viral nucleic acids, which is faster than real-time quantitative PCR (qPCR). And the results could be interpreted through either real-time fluorescence or naked-eye visualization. The limit of detection (LOD) of the assay was demonstrated to be 6.5 copies per reaction and no cross-reactivity with other pathogens such as HSV, EBV, CVA16, EV-A71, and MV was found. Furthermore, when evaluated using 113 clinical samples, the assay achieved 100% sensitivity (71/71) and 100% specificity (42/42) compared to the qPCR.

conclusionsIn resource-limited settings, our method requires only a portable heat block or water bath and a blue light or ultraviolet flashlight for visual detection of MPXV, making it highly accessible. The integration of LAMP and CRISPR/Cas12b provides a robust, user-friendly platform for point-of-care testing, with promising potential for the rapid molecular diagnosis of infectious diseases.
