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, nanocomposites based on polyvinylpyrrolidone (PVP) and sodium alginate (NaAlg) in a 30/70 wt% ratio were successfully prepared using the solution casting method and reinforced with multi-walled carbon nanotubes (MWCNTs). The effect of MWCNT incorporation on the structural, optical, dielectric, and electrical properties of the pristine PVP/NaAlg blends was comprehensively investigated. XRD patterns showed that the incorporation of MWCNTs enhanced the amorphous nature of the polymeric blend. Fourier transform infrared (FTIR) spectra showed the characteristic vibrational bands of PVP and NaAlg, with noticeable shifts and intensity changes upon MWCNT loading, suggesting strong interfacial interactions. These interactions are attributed to hydrogen bonding between PVP (C = O) and NaAlg (–OH, –COOH) groups, in addition to π–π stacking and dipole–π interactions with MWCNTs. UV–vis spectroscopy demonstrated a gradual increase in optical absorption accompanied by a redshift, consistent with improved light-harvesting capability. The optical band gap decreased from 4.25 to 2.73 eV (indirect) and from 5.01 to 4.68 eV (direct). Moreover, both AC and DC conductivities, as well as dielectric properties, increased with higher MWCNT concentrations, evidencing enhanced charge transport and polarization behavior. The DC conductivity rose from 2.00 × 10⁻¹⁰ to 1.15 × 10⁻⁵ S·cm⁻¹, while the dielectric constant increased from 10 to 1.15 × 10⁵, reflecting the remarkable energy storage capability of the prepared films. The electrical conduction process follows the correlated hopping mechanism. These findings highlight the potential of PVP/NaAlg–MWCNT nanocomposite films as promising candidates for next-generation optoelectronics and energy storage applications.
