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 proteins have become essential tools in molecular and biological applications. Here, we present a novel fluorescent protein isolated from warm water coral, Cyphastrea microphthalma. The protein, which we named vivid Verde fluorescent protein (VFP), matures readily at 37 degrees C and emits bright green light. Further characterizations revealed that VFP has a tendency to form dimers. By creating a homology model of VFP, based on the structure of the red fluorescent protein, DsRed, we were able to make mutations that alter the protein's oligomerization state. We present two proteins, mVFP and mVFP1, that are both exclusively monomeric, and one protein, dVFP, which is dimeric. We characterized the spectroscopic properties of VFP and its variants in comparison with enhanced green fluorescent protein (EGFP), a widely used variant of GFP. All the VFP variants are at least twice as bright as EGFP. Finally, we demonstrated the effectiveness of the VFP variants in both in vitro and in vivo detection applications.
