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 optical control of a biological system has been challenging, although the control of the energy transfer and isomerization reaction has been successfully demonstrated. Here, we report on our studies of ultrafast electron-transfer (ET) dynamics in a protein flavodoxin as a function of optical pump-pulse chirp. With a transform-limited excitation pulse in 25 femtoseconds, we observed the excited-state wave packet dynamics in ET reactions with a dephasing time within 1 ps. By modulating the phase of the excitation pulses, the ultrafast ET dynamics was found to change from 100 to 300 fs due to the different wave packets prepared by chirped pulses. We further found that the coherent control through the modulated wave packets can propagate into the subsequent back ET reactions resulting in the dynamics varying from 500 to 800 fs. This successful demonstration of coherent controlled ET reactions paves the way to control a variety of complex ET processes in chemical and biological systems.
