A twisted chromophore powers a turn-on fluorescent protein chloride sensor.

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
Fluorescent proteins (FPs) are noninvasive genetically encodable probes that have revolutionized bioimaging and health fields with vivid images and an ever-growing repertoire from jellyfish to sea anemones and corals. Inside the protein matrix, chromophore nonplanarity and flexibility have long been argued to govern the fluorescence efficiency of FPs, yet their fundamental roles and relative importance have been elusive which hinder the rational design of versatile FPs and biosensors. Herein, we tackle this central question by investigating two recently engineered FP-based turn-on chloride (Cl
