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
This study presents a proof-of-concept electrochemically modulated surface plasmon wave (EC-SPW) immunosensor for highly sensitive detection of gram-negative endotoxins in whole blood. Our innovative immunosensor uses an electrochemically modulated optical signal from a surface plasmon wave, which is paired with a pre-conjugated redox reporter dye. The biosensor, embedded in a micro-electrochemical flow cell, employs methylene blue as a redox-active probe due to its reversible refractive index changes during redox transitions, which amplify the optical signal for enhanced sensitivity. By integrating our transduction sensing platform with a sandwich bioassay format, we achieve an exceptional detection limit of 0.048 EU/ml for gram-negative endotoxins in whole blood samples. The sensor demonstrates excellent reproducibility and selectivity in complex blood matrices, highlighting its potential for translation to authentic clinical samples. These findings establish the EC-SPW platform as a promising tool for rapid, sensitive, and clinically relevant pathogen detection, paving the way for improved diagnostics in infectious disease management.
