Zwitterion-Based Polymeric Carriers for Efficient Drug Delivery across Biological Barriers.
Review in Polymer science & technology (Washington, D.C.), 2026. 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
Polymeric carriers, by virtue of their tunable physicochemical properties, serve as critical platforms for drug delivery. To enhance therapeutic efficacy, considerable effort has been devoted to functionalizing polymeric carriers and exploring alternative routes of administration. However, regardless of the administration modality, polymeric carriers must overcome multiple physiological barriers during delivery. In this context, zwitterionic-rich polymeric carriers exhibit superior penetration across physiological barriers, attributable to their remarkable hydration capacity and resistance to protein adsorption. Understanding how the zwitterion structure governs barrier penetration is critical for designing drug delivery systems with enhanced tissue targeting. This review summarizes the design strategies of zwitterion-based polymeric carriers, focusing on their structure-activity relationships and mechanisms for overcoming specific physiological barriers via different administration routes. Finally, we provide perspectives on harnessing artificial intelligence for the intelligent design of zwitterion-based polymeric carriers toward their accelerated clinical translation.
