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
Core-twisted perylene diimides (PDIs) are chiral organic dyes that may be exploited for self-assembled chiroptical materials or for the enantioselective recognition and sensing of chiral substrates. Discrete self-assembled dimers and host-guest complexes of core-twisted perylene diimides are important for furthering our understanding of this supramolecular chemistry, yet they are rare because the twisted perylene core significantly weakens intermolecular π-π interactions with the PDI's π-surface. To address this challenge, we have installed hydrogen bond donor groups in the PDI's bay positions, which direct the formation of a robust, co-facial and homochiral intermolecular PDI dimer. The structure of this discrete dimer is distinct from previous aggregates of non-planar PDIs that utilize the imide position for hydrogen bonding. We also uncover the potential of core-twisted, dicationic PDIs for the enantioselective recognition and chiroptical sensing of chiral anions and investigate the basis of this response via chiral complementarity in the discrete host-guest complex.
