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

Purity has been fundamental to the fabrication of high-performance semiconductors, spanning from precursors to reaction atmospheres. Emerging thermally evaporated perovskites involving precise control impose even stricter requirements on the purity of the vapor atmosphere. Compared to the purified solvent for the reaction atmosphere in the solution-based method, efficient and effective vapor purification remains unexplored. Here, we report one-step vapor purification for a pure atmosphere with less than one percent detrimental impurity. The in-situ residual gas analysis was employed to emphasize the complexity of the gas-phase composition and reveal the impurity reaction competition during the purification. The pre-control of the vapor atmosphere enabled a record external quantum efficiency over 20% for a thermally-evaporated perovskite light-emitting diode (PeLED) based on defect-suppressed FA
