Ultra-sensitive low-frequency dual-mode humidity sensor using a methyl red-PVA-graphene oxide composite.
Article in RSC advances, 2026. 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
In this study, a novel ternary composite (MPG), composed of methyl red (MR), polyvinyl alcohol (PVA), and graphene oxide (GO), is synthesized and employed for the fabrication of a humidity sensor. To explore its potential for humidity sensing applications, the structural and morphological characteristics of the MPG composite were analyzed using SEM, XRD, FTIR, and UV-visible spectroscopy. The composite demonstrated a well-integrated, crosslinked microstructure enriched with functional groups and carbon-based elements, which are highly conducive to water molecule adsorption. A 678 nm thick MPG film was deposited onto an interdigitated electrode
