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

We have investigated whether the expression of carbonic anhydrase genes (Cah1 and Cah2) is regulated by a circadian clock in Chlamydomonas. When cells were grown in ordinary air under 12 h light/12 h dark (LD) cycles, the levels of the Cah2 mRNA hardly altered during the cycles, while the Cah1 mRNA showed a strong diurnal rhythm. The rhythm of about 24 h continued at least 3 days even under continuous light. Temperature compensation of the rhythm was demonstrated, using cultures maintained at 16, 22, and 28 degrees C. These results indicate that the abundance of the Cah1 transcript is controlled by a circadian clock.
