Article in Advanced healthcare materials, 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
The development of multifunctional electro-spun nanofibrous mats has been explored as an effective platform for implantable localized cancer treatment because they provide a supportive matrix to regenerate tissues and deliver encapsulated anticancer drugs to suppress the proliferation of cancer cells. However, conventionally designed nanofibrous scaffolds present several critical challenges, particularly delayed and uncontrolled release of drug molecules due to inefficient crosslinks. Herein, we report a robust approach with the synthesis of a new phenyl diboronic acid crosslinker bearing an acid-cleavable Schiff base linkage to develop dual acidic pH-responsive degradable e-spun nanofibrous mats. The dual smart mats crosslinked with both acid-labile imine and boronic ester linkages, being structurally stable in a physiological pH, rapidly degrade through their acid-catalyzed hydrolysis in an acidic environment, leading to the enhanced release of encapsulated anticancer drugs. Furthermore, doxorubicin-loaded mats have desired antitumoral activity and hemocompatibility, while empty ones are biocompatible. These results demonstrate the great potential of dual acidic pH-responsive degradable e-spun nanofibrous mats as implantable localized drug delivery scaffolds for cancer chemotherapy.
