Article in ChemPlusChem, 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
Various industrial sectors require the development of biodegradable polymer blends with good interfacial adhesion, melt processability, mechanical performance, water, and gas barrier properties. To achieve these objectives, research efforts are focused on the discovery of promising alternatives to conventional compatibilizers. Recently, ionic liquids (ILs) have emerged as innovative compatibilizing agents due to their infinite possible combinations. Here, biopolymer blends based on poly(butylene-adipate-co-terephthalate)/poly(lactic acid) (PBAT/PLA) blends were processed by melt extrusion process using glycine betaine-based ILs as more environmentally friendly interfacial agents. In fact, only 1 wt% of ILs was incorporated into PBAT/PLA blends, leading to a co-continuous morphology characterized by the formation of PLA fibrils with various thicknesses and lengths, having a significant influence on the rheological, mechanical, water, and gas barrier properties. Then, we have demonstrated that the use of these ILs induced good mechanical performance (Young's modulus ~540 MPa, % strain: 270%-400%), combined with a reduction of almost 10 times in water vapor permeability (WVP). In addition, for a better understanding, the prediction of the permeability to gas of the formulations was performed by using the Nielsen model and compared to the experimental values (40%-75%), highlighting a good correlation between both methods.
