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 gene encoding the homologue of the catalytic subunit of the Ca2+/calmodulin-regulated protein phosphatase 2B (calcineurin A) has been isolated from Aspergillus nidulans. This gene, cnaA+, is essential in this fungal system. Analysis of growth-arrested cells following gene disruption by homologous recombination reveals that they are blocked early in the cell cycle. The cnaA+ gene encodes a 2.5 kb mRNA and the deduced protein sequence is highly homologous to the calcineurin A subunit of other species. The mRNA varies in a cell cycle-dependent manner with maximal levels found early in G1 and considerably before the G1/S boundary. As calmodulin is also essential for A.nidulans cell cycle progression and levels rise before the G1/S boundary, our data suggest that calcineurin may represent a primary target for calmodulin at this cell cycle transition point.
