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

Light-driven molecular motors undergo directional motions upon the input of external energy and represent archetypical molecular machines. So far, such motors have functioned via light-induced bond rotations, where directionality is dictated by a fixed source of asymmetry. During the operation cycle, no further structural changes occur, other than the rotation itself. Here we disclose a highly effective mechanism for light-driven motor rotation involving constitutional alteration and reversible proton transfer. Associated with this unusual mechanism is a particularly high energy content from the incident light that the motor retains. This feature is further exploited in a low-temperature molecular solar thermal energy storage application, where solar energy can be stored and released in a controlled fashion and tracked step by step with the naked eye. With these findings, unique possibilities emerge for the design and use of molecular motors with hitherto unknown modes of action and power.
