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

The performance of perovskite solar cells (PSCs) is critically dependent on the quality of interfaces and grain boundaries, which often lead to nonradiative recombination losses, degradation, and inefficient charge transport. Here, we introduce an asymmetric bulky cation with a dipole moment (2.48 Debye), 4-methoxyphenethylammonium bromide (MPB), at the perovskite/hole transport layer (HTL) interface in planar (n-i-p) PSCs. The MPB provides dual functionality, not only as a defect passivation agent for undercoordinated Pb
