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

Developing low-cost unipolar n-type organic thin-film transistors (OTFTs) is necessary for logic circuits. To achieve this objective, the usage of new electron-deficient building blocks with simple structure and easy synthetic route is desirable. Among all electron-deficient building units, N-oxide-functionalized bipyridines can be prepared through a simple oxidized transformation of bipyridines. However, employing N-oxide-functionalized bipyridines as the building unit to construct efficient N-type polymers has been overlooked. This gap strongly encourages us to design and synthesize two new N-oxide building blocks, 5,5'-dibromo-[2,2'-bipyridine] 1-oxide (BPyO) and 5,5'-dibromo-[2,2'-bipyridine] 1,1'-dioxide (BPyDO), through the oxidation of sp
