Neutral DNA-avidin nanoparticles as ultrasensitive reporters in immuno-PCR.
Article in The Analyst, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
We have developed an immuno-PCR based diagnostic platform which couples detection antibodies to self-assembled, ultra-detectable DNA-avidin nanoparticles stabilized with poly(ethylene glycol) to link DNA amplification to target protein concentration. Electrostatic neutralization and cloaking of the PCR-amplifiable DNA labels by avidin and PEG coating reduces non-specific "stickiness" and enhances assay sensitivity. We further optimized the detectability of the nanoparticles by incorporating four repeats of a unique synthetic DNA PCR target into each nanoparticle. Using human chorionic gonadotropin hormone (hCG) as a model analyte, this platform was able to quantitate the target hCG protein in femtomolar concentrations using only standard laboratory equipment.
