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
Objectives: Vaginal nanofibers with high surface area and tunable porosity are a promising platform for vaginal administration. Poly(vinyl alcohol) (PVA) is a widely used polymer in the pharmaceutical field due to its hydrophilic, biodegradable, non-toxic, and mucoadhesive properties. This study aimed to optimize PVA-based electrospun nanofibers for vaginal drug delivery by evaluating polymer concentration, solvent system, and collector rotation speed using a design of experiments-based approach. Materials and Methods: PVA was dissolved in distilled water (DW) at 90 °C to prepare polymer solutions; then N, N-dimethylformamide (DMF) or ethanol was added. The surface tension, viscosity, and conductivity of the polymer solutions were evaluated. For the production of nanofibers via electrospinning, the parameters selected were PVA concentrations of 7.5% and 15%, collector rotation speed of 100 and 1000 rpm, and two solvent systems (DMF: DW and ethanol: DW). Mechanical and mucoadhesive properties of nanofibers were evaluated using a texture analyzer. Results: Viscosity and conductivity increased as polymer concentration increased. An increase in PVA concentration resulted in increased tensile strength of the nanofibers, from 1.41±0.07 to 3.92±0.14 MPa ( Conclusion: The solvent system and collector rotation speed were found to influence the morphological structure of the fibers. R3 (7.5% PVA, ethanol/DW, 1000 rpm) formulation was found to be more suitable than other formulations based on its mechanical and mucoadhesive properties. It was concluded that in the production of PVA nanofibers, the rotating speed of the collector, the polymer concentration, and the solvent system directly affect the mechanical and mucoadhesive properties of the nanofibers.
