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

Preliminary observations have suggested mild behavioral changes and a morphological disruption of brain histology in 1.5-year-old carbonic anhydrase IX (CA IX)-deficient (Car9 (-/-)) mice. These findings led us to design a 1-year follow-up study in which the behavior and brain histology of Car9 (-/-) and wild-type mice were monitored. Morphological analysis revealed vacuolar degenerative changes in the brains of Car9 (-/-) mice. The changes became visible at the age of eight to ten months. Behavioral tests showed that the Car9 (-/-) mice exhibited abnormal locomotor activity and poor performance in a memory test. To further identify the transcriptomic responses to CA IX deficiency in the brain, genome-wide cDNA microarray analyses were performed. Thirty-one and 37 genes were significantly up- or down-regulated, respectively, in the brain of Car9 (-/-) mice compared to the wild-type mice. Functional annotation revealed that the genes with increased expression were involved in several processes, such as RNA metabolism, and the genes with reduced expression were implicated in other important processes, including the regulation of cellular ion homeostasis. Notably, the biological processes "behavior" and "locomotory behavior" were the two prominent terms overrepresented among the down-regulated genes, which is consistent with the behavioral phenotype. These results suggest that CA IX may directly or indirectly play novel functions in brain tissue. Furthermore, the brain phenotype of Car9 (-/-) mice seems to be age-dependent. The results indicate that the functional changes precede the microscopic alterations in the brains of Car9 (-/-) mice.
