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

Auger heating represents a major bottleneck for hot carrier (HC) relaxation in colloidal quantum wells (CQWs), delaying carrier accumulation in band-edge states and diminishing performance in light-emitting applications. To address this issue, we introduce copper doping in CdSe CQWs to create midgap states, which efficiently suppresses Auger heating without altering their intrinsic structural or optical properties. Ultrafast spectroscopy demonstrates pump-intensity-invariant HC cooling dynamics in Cu-doped CQWs, occurring within ∼0.21 ps at a consistent energy-loss rate of ∼610 meV/ps, even under high exciton densities (<N> ≈ 4). In contrast, undoped samples exhibit significant cooling deceleration as excitation intensity increases. Combined experimental and theoretical results attribute this ultrafast cooling to rapid hole trapping at Cu
