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
Donor-acceptor (D-A) conjugated polymers are promising materials for organic transistors including organic field-effect transistors (OFETs) and organic electrochemical transistors (OECTs). The aggregated structure of D-A conjugated polymer films, which strongly depends on the crystallization process, is crucial for the device performance. However, the crystallization of D-A conjugated polymers is complicated during solution processing, and the optimal film structure is various in different applications. Therefore, it is significantly important to reveal the relationship between the processing conditions and the resulting aggregated structures. This review provides a systematic understanding of how to control the aggregated structure of D-A conjugated polymer films from the fundamental mechanisms of polymer crystallization. We first discuss the possible nucleation and growth mechanisms of D-A conjugated polymers based on traditional theories or models and current findings. Then, recent progress in controlling the structure of D-A conjugated polymer films for OFETs and OECTs is reviewed. D-A conjugated polymers generally adopt chain-extended crystallization due to their strongly rigid backbone, which makes homogeneous nucleation difficult. A common strategy to control the aggregated structure of D-A conjugated polymer films is to manipulate the heterogeneous nucleation process by tuning the pre-aggregation. Besides, the effect of the crystallization rate and complicated conditions on the aggregated structure of D-A conjugated polymer films is also discussed. Finally, a concise summary is provided, followed by some current challenges in controlling the aggregated structure of D-A conjugated polymer films.
