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

Colloidal quantum dot (QD) films inherently exhibit a high Seebeck coefficient (α) and low thermal conductivity (κ), making them attractive for thermoelectric (TE) applications. However, achieving high electrical conductivity (σ) while preserving these advantages remains challenging due to limited interdot coupling and high-temperature treatments that compromise interdependent TE parameters. Herein, room-temperature inter-dot bridging of individual PbS QDs is demonstrated, leading to unprecedented electronic tunability and significant improvements in the n-type TE figure of merit (ZT). By tailoring the hydride concentration, gradual removal of surface ligands is induced, resulting in strengthened electrical coupling, structural ordering, and n-type doping of QD films. Consequently, σ is precisely modulated from ≈10
