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

The chain conformation of conjugated oligomers are critical for constructing ultrafine fluorescent nanoprobes with outstanding sensing performances owing to their suitable molecular flexibility and fine-tuned aggregation state. Herein, a series of pyrenyl-pyridine oligomers (OPPs) were designed and conveniently prepared by one-pot Sonogashira coupling of flexible 2,6-bis(ethynyl)pyridine with different rigid pyrene unit. Novel fluorescent nanoprobes (OPPNPs, ca. 2.50-25.4 nm in diameter) were hence readily fabricated through a microemulsion route, showcasing significantly distinct detecting properties due to their distinctive chain conformations. In particular, ultrasmall OPP1NPs (~ 3.75 nm) bearing zig-zag-shaped 1,6-substituted pyrenyl-pyridyl conjugated chain presented superior π-π stacking, strong excimer emission and best sensing performances for Fe
