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
In molecular diagnostics, the digital polymerase chain reaction (dPCR) has been considered a promising point-of-care testing (POCT) method for the rapid and accurate analysis of respiratory infections. To improve its practical applicability, it is necessary to develop a mass-producible and reproducible dPCR system for nucleic acid partitioning; additionally, the system must provide a customized portable analysis. In this study, we report an advanced mass-production method for the fabrication of microwell array-based dPCR chips suitable for nucleic acid partitioning and a compact fluorescence signal analysis dPCR system. Based on metal mold fabrication, different microwell sizes with diameters in the 100-200 μm range and pitches in the 200-400 μm range are designed and successfully fabricated using photolithography, metal electroplating, and injection molding techniques. Additionally, a battery-operated dPCR system utilizing digitalized fluorescence signal analysis is developed for on-site detection. To verify the chip and system applicability, the infectious human coronavirus is analyzed using different nucleic acid concentrations. By evaluating the performance of the dPCR chips and system, accurate and quantitative virus analysis results are obtained, verifying the portability, easy use, and reproducibility of the chips and system. Furthermore, the detection results obtained using the fabricated chips and the developed system are similar to the results obtained using commercially available systems, verifying that the proposed dPCR chips and system exhibit sensitivity, accuracy, reliability, and reproducibility in the quantitative molecular analysis of infectious diseases.
