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

Traditional thermoelectric generators (TEGs) rely on external heat sources and heat sinks to maintain a thermal gradient and generate electrical power. Here, we present a dual phase change material (PCM) integrated TEG system that generates an internal temperature gradient without a defined hot or cold side. Two PCMs with different melting points are positioned on opposite sides of the TEG, enabling the system to create repeatable thermal hysteresis during heating and cooling cycles. To improve the thermal conductivity of the PCM, we developed a hybrid composite PCM containing graphene nanoplatelets and copper metal wool, achieving a thermal conductivity of 0.98 W m
