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
Durable polylactide (PLA)-based materials are highly pursued for replacing conventional petroleum-based plastics. However, developing a tough and heat-resistant PLA blend remains a significant challenge. Herein, a series of high-performance PLA-based blends were prepared through melt blending of bio-based polycarbonate (PC), poly-(d-lactic acid) (PDLA), and a compatibilizer (BPM). Phase morphology, crystallization behavior, mechanical properties, and thermal resistance were systematically analyzed. A novel dual heat-resistant network was constructed, comprising a continuous PC phase and PDLA/PLA stereocomplexation. In this network, the stereocomplexation creates a 3D network restricting the amorphous PLA chain mobility, while the PC phase acts as a heat-resistant framework, collectively enhancing thermal stability. Moreover, the addition of BPM enhances the toughness and interfacial adhesion between PC and PLA phases, resulting in substantial improvements in mechanical properties. The optimized blend achieved a heat deflection temperature of 106.5 °C, an impact strength of 7.5 kJ/m
