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 pacemaker of the Neurospora circadian clock is composed of a transcriptional-translational feedback loop that has been intensively studied during the last two decades. Invaluable information has been derived from measuring the expression of the central clock component frequency (frq) under liquid culture conditions. Direct analyses of frq mRNA and protein levels on solid media - where overt circadian rhythms are normally visualized - have not been trivial due to technical issues. Nevertheless, a frq promoter-luciferase reporter has recently allowed the study of frq transcription under these conditions. It is known that FRQ undergoes extensive posttranslational modifications, and changes in its levels provide important information regarding the clockworks. Here we describe a FRQ-luciferase translational fusion reporter that directly tracks FRQ levels, granting access to a better understanding and analysis of FRQ dynamics in vivo. More generally the method, which allows the investigator to follow continuous gene expression in real time in a spatially and temporally unrestricted manner, should be widely applicable to analyses of environmentally and developmentally regulated gene expression in ascomycete filamentous fungi as well as in basidiomycetes.
