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.
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
Due to the deficiency of anchoring sites (i.e., hydroxyl groups), self-assembled monolayers (SAMs) pose a significant challenge for achieving dense and uniform coverage on textured substrates, thereby hindering the development of perovskite/silicon tandem solar cells. Here, we develop an in-situ carbon incorporation strategy for polysilicon-based tunnel recombination interconnection layers to enhance SAM adsorption and anchoring. Carbon-incorporated polysilicon exhibits a higher surface hydroxyl group density and enhanced hydrophilicity, facilitating SAM adsorption and forming robust SAM anchoring. This leads to improved uniformity and continuity of SAM coverage, along with enhanced perovskite crystallization, resulting in pinhole‑free and denser perovskite deposition on textured substrates. Moreover, the strategy further adjusts the energy level alignment of the SAM surface, facilitating hole extraction.
