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

Mutations in the disconnected (disco) gene act to disrupt neural cell patterning in the Drosophila visual system. These mutations also affect adult locomotor activity rhythms, as disco flies are arrhythmic under conditions of constant darkness (DD). To determine the state of the circadian pacemaker in disco mutants, we constructed with pers double mutants (a short period allele of the period gene) and assayed their behavioral rhythms in light-dark cycles (LD), and their biochemical rhythms of period gene expression under both LD and DD conditions. The results demonstrate that disco flies are rhythmic, indicating that they have an active circadian pacemaker that can be entrained by light. They also suggest that disco mutants block or interfere with elements of the circadian system located between the central pacemaker and its outputs that mediate overt rhythms.
