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

Transcription factor GATA-1 is essential for red blood cell maturation and, therefore, for survival of developing mouse embryos. GATA-1 is also expressed in megakaryocytes, mast cells, eosinophils, multipotential hematopoietic progenitors and Sertoli cells of the testis, where its functions have been elusive. Indeed, interpretation of gene function in conventional knockout mice is often limited by embryonic lethality or absence of mature cells of interest, creating the need for alternate methods to assess gene function in selected cell lineages. Emerging strategies for conditional gene inactivation through site-specific recombinases rely on the availability of mouse strains with high fidelity of transgene expression and efficient, tissue-restricted DNA excision. In an alternate approach, we modified sequences upstream of the GATA-1 locus in embryonic stem cells, including a DNase I-hypersensitive region. This resulted in generation of mice with selective loss of megakaryocyte GATA-1 expression, yet sufficient erythroid cell levels to avoid lethal anemia. The mutant mice have markedly reduced platelet numbers, associated with deregulated megakaryocyte proliferation and severely impaired cytoplasmic maturation. These findings reveal a critical role for GATA-1 in megakaryocyte growth regulation and platelet biogenesis, and illustrate how targeted mutation of cis-elements can generate lineage-specific knockout mice.
