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

CIB1 is a 22-kDa calcium binding, regulatory protein with approximately 50% homology to calmodulin and calcineurin B. CIB1 is widely expressed and binds to a number of effectors, such as integrin alphaIIb, PAK1, and polo-like kinases, in different tissues. However, the in vivo functions of CIB1 are not well understood. To elucidate the function of CIB1 in whole animals, we used homologous recombination in embryonic stem cells to generate Cib1(-/-) mice. Although Cib1(-/-) mice grow normally, the males are sterile due to disruption of the haploid phase of spermatogenesis. This is associated with reduced testis size and numbers of germ cells in seminiferous tubules, increased germ cell apoptosis, and the loss of elongated spermatids and sperm. Cib1(-/-) testes also show increased mRNA and protein expression of the cell cycle regulator Cdc2/Cdk1. In addition, mouse embryonic fibroblasts (MEFs) derived from Cib1(-/-) mice exhibit a much slower growth rate compared to Cib1(+/+) MEFs, suggesting that CIB1 regulates the cell cycle, differentiation of spermatogenic germ cells, and/or differentiation of supporting Sertoli cells.
