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

Pyroelectric devices hold promise for thermal energy harvesting and sensing. While previous studies have focused on the intrinsic pyroelectric response, they neglect the interfacial pyroelectric effect at the electrode-material interface, leading to an overestimation of the intrinsic contribution to pyroelectricity. By leveraging the reversibility of the intrinsic effect and the irreversibility of the interfacial effect, we propose a method that uses polarization reversal measurements to distinguish between them. By calculating the contributions of the two effects for different ferroelectric films, it is observed that the intrinsic and interfacial pyroelectric effects dominate in PbTiO
