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 conditions have substantial effects on living organisms through a variety of aspects of individual life, such as survival, feeding, reproduction, stress responses, and behavioral rhythms. In this study, to evaluate the importance of light conditions for nocturnal fish, the spontaneous spatial preferences and swimming activity of the loach (Misgurnus anguillicaudatus), a nocturnal freshwater fish, was investigated using controlled light intensity gradients. Despite observing individual variations in dark preference responses, these preferences were not consistent at the individual level when measured repeatedly at four-week intervals. This suggests that individual differences in light/dark preferences may reflect state-dependent variations rather than fixed traits. When the light intensity in the bright area was changed from 2.4 to 400 µW/cm
