1 · What the graph read from it

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.

2 · The registry

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 massive accumulation of electronic waste (e-waste) globally demands sustainable strategies for printed circuit boards (PCBs), a goal currently hindered by the pervasive use of irreversibly cured epoxy resins. Here, a kinetically inert covalent adaptable network (CAN) is designed for recyclable high-performance PCB based on gem-dimethyl dithioketal (gTK) epoxy resins. The gem-dimethyl effect significantly enhances the stability of gTK bonds through steric hindrance, kinetically blocking undesirable acidolysis and heat-induced exchange reactions. The fabricated gTKPCB satisfies the demanding commercial specifications, exhibiting robust thermomechanical stability (~ 220 °C), chemical resistance, and highly reliable electrical interconnection under long-term thermal conditions (105 °C, 90 d). Crucially, gTKPCBs undergo oxidation-specific degradation in H
