Biophysical Characterization of Genetically Encoded Voltage Sensor ASAP1: Dynamic Range Improvement.
Article in Biophysical journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Recent work has introduced a new fluorescent voltage sensor, ASAP1, which can monitor rapid trains of action potentials in cultured neurons. This indicator is based on the Gallus gallus voltage-sensitive phosphatase with the phosphatase domain removed and a circularly permuted GFP placed in the S3-S4 linker. However, many of the biophysical details of this indicator remain unknown. In this work, we study the biophysical properties of ASAP1. Using the cut-open voltage clamp technique, we have simultaneously recorded fluorescence signals and gating currents from Xenopus laevis oocytes expressing ASAP1. Gating charge movement and fluorescence kinetics track closely with each other, although ASAP1 gating currents are significantly faster than those of Ciona intestinalis voltage-sensitive phosphatase. Altering the residue before the first gating charge removes a split in the ASAP1 QV curve, but preserves the accelerated kinetics that allow for the faithful tracking of action potentials in neurons.
