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
Self-assembled monolayers suffer from the insufficient electrical conductivity, stemming from their ultrathin nature and disordered molecular orientation. Here we report a π-skeleton unit of 3,6-dibenzothiophen-9H-carbazol to building a self-assembled multilayer (SAMUL) that exhibits superior carrier transport and outstanding resistance to external stimuli. The π-expanded skeleton effectively enhanced the molecular crystallinity and face-on orientation, which successfully activated a large π-electron conjugated network within SAMULs. This conjugated network structure greatly broadens the delocalization region of free radicals, which not only significantly enhances the electrical conductance and hole-transporting capability, but also reinforces the photochemical stability. Consequently, a record-high efficiency of 21.13% (certified as 20.77%) with a notable fill factor of 83.48% was achieved for binary organic solar cells. This work provides a new inspiration for the molecular skeleton design in organic electronics.
