Influence of Relative Humidities on Highly Electrically Conductive Polyelectrolyte Multilayer Films.
Article in Langmuir : the ACS journal of surfaces and colloids, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Understanding charge transport mechanisms are crucial when making ultrathin layer-by-layer (LbL) films with high electrical conductivity. We investigate the influence of the relative humidity (RH), and thus, the water content of the films. We study polyelectrolyte multilayers made from PEDOT:PSS (poly-3,4-ethylenedioxythiophen:poly styrenesulfonate) and carbon nanotubes (CNTs) as polyanion layers. All films investigated showed the highest conductivity at RH ≈ 40%. At RH ≤ 20%, UV/vis/IR absorption measurements of PEDOT:PSS films are typical for strongly charged PEDOT (as found in spin-coated PEDOT:PSS films), the direct current (DC) conductivity is low (10
