Kinetics and Retention of Polystyrenesulfonate for Proteoglycan Replacement in Cartilage.
Article in Biomacromolecules, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Tissue hydration provides articular cartilage with dynamic viscoelastic properties. Early stage osteoarthritis (OA) is marked by loss of proteoglycans and glycosaminoglycans (GAG), lowering fixed charge density, and impairing tissue osmotic function. The most common GAG replacement, chondroitin sulfate (CS), has failed to show effectiveness. Here, we investigated a synthetic polyelectrolyte, poly(styrenesulfonate) (PSS), both as a model compound to investigate polyelectrolyte transport in cartilage, and as a potential candidate to restore bulk fixed charge density in cartilage with GAG loss. Through bovine explants and histology, we determined zonal-based effective diffusion coefficients for three different molecular weights of PSS. Compared to CS, PSS was retained longer in GAG-depleted cartilage in static and compression-based desorption experiments. We explained enhanced solute performance of PSS by its more compact morphology and higher charge density by small-angle X-ray scattering. This study may improve design of GAG mimetic molecules for repairing osmotic function in OA cartilage.
