Trace Analysis of Emerging Virus: An Ultrasensitive ECL-Scan Imaging System for Viral Infectious Disease.
Article in ACS omega, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Emerging infectious diseases have brought a huge impact on human society in recent years. The outbreak of Zika virus (ZIKV) in the Americas resulted in a large number of babies born with microcephaly. More seriously, the Coronavirus Disease 2019 (COVID-19) was globally spread and caused immeasurable damages. Thus, the monitoring of highly pathogenic viruses is important to prevent and control emerging infectious diseases. Herein, a dendritic polymer probe-amplified ECL-scan imaging system was constructed to realize trace analysis of viral emerging infectious diseases. A dendritic polymer probe was employed as the efficient signal emitter component that could generate an amplified ECL signal on the integrated chip, and the signal was detected by a single-photon level charge coupled device-based ECL-scan imaging system. With this strategy, the ZIKV in a complex system of blood, urine, and saliva was detected. The results indicated that a high sensitivity of 50 copies and superior specificity were achieved. Furthermore, this strategy realized highly sensitive detection (10 copies) of the S and N protein gene sequence of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov2) and spiked pseudovirus samples. Thus, the dendritic polymer probe-amplified ECL-scan imaging system suitably met the strict clinical requirements for trace analysis of an emerging virus, and thus has the potential to serve as a paradigm for monitoring emerging infectious diseases.
