Optimized heparin adsorption using macroporous zeolites: A comprehensive study.
Article in Heliyon, 2025. 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
Heparin is a highly valuable active pharmaceutical ingredient, typically derived from porcine intestinal mucosa. Traditionally, various commercial resins have been used as adsorbents for heparin extraction; however, there has been growing interest in exploring more cost-effective adsorbents in recent years to improve heparin recovery. Zeolites, a typical aluminosilicate known for their high surface area, porosity, and thermal stability, were selected for evaluation in this study. We investigated the performance of two different zeolites, CBV901 and CBV10A, in recovering heparin. Our findings indicate that the CBV901 zeolite exhibits excellent efficiency (44 %) along with capacity (23.3 mg.g-1) for adsorption when used with porcine intestinal mucosa. A mechanistic analysis using kinetic and thermodynamic models revealed that the surface conditions were favorable for heparin adsorption. Additionally, we examined the effects of various conditions including adsorption time, as well as sorbent reusability for recovery process refinement.
