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 beta class of the carbonic anhydrase (CA) enzyme family has been found in plants, yeast, bacteria and algae, but not in animals. Also, little is known concerning the CAs of C. elegans. Genes possibly encoding beta-CAs were revealed by in silico analysis of the C. elegans genome. Amino acid sequence and 3D structure analysis revealed a resemblance to both plant and cab-type beta-CAs. Temporal expression patterns of the two genes, as well as changes in expression levels under different atmospheric conditions (stress) were analyzed by real-time RT-PCR. Recombinant enzymes, expressed in E. coli were used for in vitro measurement of CA activity, while a yeast complementation experiment was performed in order to assess their ability to complement the function of S. crevisieae beta-CA (NCE103) in vivo. RNAi by feeding was performed on wild-type populations that were then examined for a visible phenotype under normal or various stress conditions (pH, CO(2)/O(2)). Two genes possibly encoding beta-CAs were revealed (bca-1 and y116a8c.28). Their products contain elements of both plant and cab-type CAs. Both assays showed that Y116a8c.28 is an active CA. Both genes showed significant levels of transcript accumulation during development, while they also responded to the stress conditions. No visible phenotype was scored under normal or stress conditions.
