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

While [4-(3,6-Dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz) self-assembled monolayers (SAMs) enable high-performance inverted perovskite solar cells (PSCs), their sparse coverage on nickel oxide (NiOx) induces heterogeneous interfacial charge distribution at the buried perovskite interface. This increases non-radiative recombination, ultimately limiting device performance. Herein, benzylphosphonic acid (BPPA) is added, a small molecule featuring a phosphonic acid group, into Me-4PACz to construct a co-assembled monolayer (Co-SAM) with enhanced molecular ordering on NiOx. The resulting compact Co-SAM hole transport layer (HTL) simultaneously improves electrical conductivity, hole mobility, and interfacial energy level alignment, facilitating efficient hole injection. Moreover, BPPA's phosphonic acid groups enable bifacial passivation: coordinating NiOx surface defects while chelating uncoordinated Pb
