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

Staphylococcus epidermidis (SE) and Staphylococcus aureus (SAU), comprising 50% of pathogenic bacteria in clinical blood isolates, demand precise detection for infection control. We present a label-free terahertz (THz) metasurface biosensor enabling simultaneous quantification and speciation of these Gram-positive pathogens. A tailored metasurface enhances THz wave-bacteria interaction through sharp resonance, creating quantitative correlations between resonance shifts and bacterial fluid dosage. Distinct linear regression slopes (SAU: 105.90 GHz/μL, SE: 45.14 GHz/μL) permit species differentiation, achieving specificity without biochemical labeling. This platform eliminates complex surface functionalization, reducing preparation time compared to ELISA-based methods while maintaining high sensitivity (theoretically 135.1 GHz/RIU, at a thickness of 3 μm, and experimentally 556 GHz/cell μm
