One-Step Label-Free Electrochemical Lateral Flow Immunosensor for SARS-CoV‑2 Antigen Detection.
Article in ACS measurement science au, 2025. 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
Rapid and ultrasensitive diagnostic tests for COVID-19 remain crucial, yet conventional lateral flow antigen kits are limited by their reliance on labeled probes and suboptimal sensitivity at low viral loads. Here, we present a label-free electrochemical antigen test kit (free-EATK) that enables one-step detection of the SARS-CoV-2 N protein without the need for conjugate pads, covalently labeled redox probes, or signal normalization schemes. The system integrates a nitrocellulose-coated electrode, a redox pad preloaded with [Ru-(NH
