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 ability to detect and adapt to different levels of ambient light is critical for animal survival. Light detection is the basis of vision, but light also regulates eye development and drives several non-image-forming functions, including synchronizing circadian rhythms to the daily light/dark cycle, restricting pupils in response to changes in light intensity, and modulating mood in response to light. Until the early 2000s, these functions were thought to be solely mediated by ocular photoreceptors. However, neuropsin (OPN5), a UV-sensitive opsin, has been receiving growing attention, as new methods have revealed previously unappreciated functions of OPN5. In fact, OPN5-mediated extraocular and deep-brain photoreception have recently been described for the first time in mammals. This review aims to synthesize current knowledge of the properties and functions of OPN5 across vertebrates.
