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

Fluorescent flippers are twisted push-pull mechanophores that report planarization with red-shifted absorption and an increase in fluorescence intensity and lifetime. Until today, their planarization by physical forces has focused on compression to visualize physical forces in biology. Here, we show that planarization can also be achieved by stretching of flipper probes that are equipped with tethers in their core and to visualize mechanical stress in polymeric materials. The synthesis of dithieno-[3,2-
